| AAT3200 OmniPowerTM LDO Linear Regulator General Description The AAT3200 PowerLinear OmniPower low dropout (LDO) linear regulator is ideal for systems where a low-cost solution is required. This device features extremely low quiescent current, typically 20A. Dropout voltage is also very low, typically 200mV. The AAT3200 has output short-circuit and over-current protection. In addition, the device has an over-temperature protection circuit which will shut down the LDO regulator during extended over-current events. The AAT3200 is available in a space-saving, Pbfree SC59 or SOT-89 package (for applications requiring increased power dissipation). The device is rated over a -40C to +85C temperature range. Since only a small, 1F ceramic output capacitor is required, the AAT3200 is a truly cost-effective voltage conversion solution. The AAT3201 is a similar product for this application, especially when a shutdown mode is required for further power savings.

The advanced circuit design of the AAT3200 has been optimized for use as the most cost-effective solution. The typical quiescent current level is just 20A and it does not increase with increasing current load. The LDO also demonstrates excellent PSRR and load and line transient response characteristics. The LDO regulator output has been specifically optimized to function with low-cost, low-ESR ceramic capacitors. However, the design will allow for operation with a wide range of capacitor types. The AAT3200 has complete short-circuit and thermal protection. The integral combination of these two internal protection circuits gives the AAT3200 a comprehensive safety system to guard against extreme adverse operating conditions. Device power dissipation is limited to the package type and thermal dissipation properties. Refer to the Thermal Considerations section of this datasheet for details on device operation at maximum output load levels. 8 3200.2006.02.1.4 AAT3200 OmniPowerTM LDO Linear Regulator Applications Information To assure the maximum possible performance is obtained from the AAT3200, please refer to the following application recommendations. If large output current steps are required by an application, then an increased value for COUT should be considered. The amount of capacitance needed can be calculated from the step size of the change in the output load current expected and the voltage excursion that the load can tolerate. The total output capacitance required can be calculated using the following formula: I x 15F V Input Capacitor Typically, a 1F or larger capacitor is recommended for CIN in most applications. A CIN capacitor is not required for basic LDO regulator operation. However, if the AAT3200 is physically located any distance more than one or two centimeters from the input power source, a CIN capacitor will be needed for stable operation. CIN should be located as closely to the device VIN pin as practically possible. CIN values greater than 1F will offer superior input line transient response and will assist in maximizing the highest possible power supply ripple rejection. Ceramic, tantalum, or aluminum electrolytic capacitors may be selected for CIN. There is no specific capacitor equivalent series resistance (ESR) requirement for CIN. For 150mA to 250mA LDO regulator output operation, ceramic capacitors are recommended for CIN due to their inherent capability over tantalum capacitors to withstand input current surges from low impedance sources such as batteries in portable devices. COUT = Where: I = maximum step in output current V = maximum excursion in voltage that the load can tolerate Note that use of this equation results in capacitor values approximately two to four times the typical value needed for an AAT3200 at room temperature. The increased capacitor value is recommended if tight output tolerances must be maintained over extreme operating conditions and maximum operational temperature excursions. If tantalum or aluminum electrolytic capacitors are used, the capacitor value should be increased to compensate for the substantial ESR inherent to these capacitor types. Output Capacitor For proper load voltage regulation and operational stability, a capacitor is required between pins VOUT and GND. The COUT capacitor connection to the LDO regulator ground pin should be made as direct as practically possible for maximum device performance. The AAT3200 has been specifically designed to function with very low ESR ceramic capacitors. Although the device is intended to operate with low ESR capacitors, it is stable over a wide range of capacitor ESR; thus, it will also work with some higher ESR tantalum or aluminum electrolytic capacitors. However, for best performance, ceramic capacitors are recommended. The value of COUT typically ranges from 0.47F to 10F; however, 1F is sufficient for most operating conditions. Capacitor Characteristics Ceramic composition capacitors are highly recommended over all other types of capacitors for use with the AAT3200. Ceramic capacitors offer many advantages over their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically has very low ESR, is lower cost, has a smaller PCB footprint, and is non-polarized. Line and load transient response of the LDO regulator is improved by using low ESR ceramic capacitors. Since ceramic capacitors are non-polarized, they are less prone to damage if incorrectly connected. Equivalent Series Resistance: ESR is a very important characteristic to consider when selecting a capacitor. ESR is the internal series resistance associated with a capacitor that includes lead 3200.2006.02.1.4 9 AAT3200 OmniPowerTM LDO Linear Regulator resistance, internal connections, capacitor size and area, material composition, and ambient temperature. Typically, capacitor ESR is measured in milliohms for ceramic capacitors and can range to more than several ohms for tantalum or aluminum electrolytic capacitors. Ceramic Capacitor Materials: Ceramic capacitors less than 0.1F are typically made from NPO or C0G materials. NPO and C0G materials generally have tight tolerance and are very stable over temperature. Larger capacitor values are usually composed of X7R, X5R, Z5U, or Y5V dielectric materials. Large ceramic capacitors (i.e., greater than 2.2F) are often available in low-cost Y5V and Z5U dielectrics. These two material types are not recommended for use with LDO regulators since the capacitor tolerance can vary by more than 50% over the operating temperature range of the device. A 2.2F Y5V capacitor could be reduced to 1F over the full operating temperature range. This can cause problems for circuit operation and stability. X7R and X5R dielectrics are much more desirable. The temperature tolerance of X7R dielectric is better than 15%. Capacitor area is another contributor to ESR. Capacitors that are physically large in size will have a lower ESR when compared to a smaller sized capacitor of equivalent material and capacitance value. These larger devices can also improve circuit transient response when compared to an equal value capacitor in a smaller package size. Consult capacitor vendor datasheets carefully when selecting capacitors for use with LDO regulators. over-current operating conditions, the output voltage would drop and the AAT3200 die temperature would increase rapidly. Once the regulator's power dissipation capacity has been exceeded and the internal die temperature reaches approximately 140C, the system thermal protection circuit will become active. The internal thermal protection circuit will actively turn off the LDO regulator output pass device to prevent the possibility of over-temperature damage. The LDO regulator output will remain in a shutdown state until the internal die temperature falls back below the 140C trip point. The combination and interaction between the shortcircuit and thermal protection systems allows the LDO regulator to withstand indefinite short-circuit conditions without sustaining permanent damage. No-Load Stability The AAT3200 is designed to maintain output voltage regulation and stability under operational noload conditions. This is an important characteristic for applications where the output current may drop to zero. An output capacitor is required for stability under no-load operating conditions. Refer to the Output Capacitor section of this datasheet for recommended typical output capacitor values. Thermal Considerations and High Output Current Applications The AAT3200 is designed to deliver a continuous output load current of 150mA for an SC59 package or 250mA for a SOT-89 package under normal operating conditions. The limiting characteristic for the maximum output load safe operating area is essentially package power dissipation and the internal preset thermal limit of the device. In order to obtain high operating currents, careful device layout and circuit operating conditions need to be taken into account. The following discussions will assume the LDO regulator is mounted on a printed circuit board utilizing the minimum recommended footprint and the printed circuit board is 0.062-inch thick FR4 material with one ounce copper. Short-Circuit and Thermal Protection The AAT3200 is protected by both current limit and over-temperature protection circuitry. The internal short-circuit current limit is designed to activate when the output load demand exceeds the maximum rated output. If a short-circuit condition were to continually draw more than the current limit threshold, the LDO regulator output voltage would drop to a level necessary to supply the current demanded by the load. Under short-circuit or other 10 3200.2006.02.1.4 AAT3200 OmniPowerTM LDO Linear Regulator At any given ambient temperature (TA), the maximum package power dissipation can be determined by the following equation: -T T PD(MAX) = J(MAX) A JA Constants for the AAT3200 are TJ(MAX), the maximum junction temperature for the device (125C) and JA = 200C/W, the SC59 thermal resistance. Typically, maximum conditions are calculated at the maximum operating temperature where TA = 85C, under normal ambient conditions TA = 25C. Given TA = 85C, the maximum package power dissipation is 200mW. At TA = 25C, the maximum package power dissipation is 500mW. The maximum continuous output current for the AAT3200 is a function of the package power dissipation and the input-to-output voltage drop across the LDO regulator. Refer to the following simple equation: PD(MAX) VIN - VOUT This formula can be solved for VIN to determine the maximum input voltage. VIN(MAX) = PD(MAX) + (VOUT x IOUT) IOUT + IGND The following is an example for an AAT3200 set for a 3.0V output: From the discussion above, PD(MAX) was determined to equal 417mW at TA = 25C. VOUT IOUT IGND = 3.0V = 150mA = 20A 500mW + (3.0V x 150mA) 150mA + 20A VIN(MAX) = VIN(MAX) > 5.5V Thus, the AAT3200 can sustain a constant 3.0V output at a 150mA load current as long as VIN is 5.5V at an ambient temperature of 25C. 5.5V is the maximum input operating voltage for the AAT3200, thus at 25C, the device would not have any thermal concerns or operational VIN(MAX) limits. This situation can be different at 85C. The following is an example for an AAT3200 set for a 3.0V output at 85C: From the discussion above, PD(MAX) was determined to equal 200mW at TA = 85C. VOUT IOUT IGND = 3.0V = 150mA = 20A 200mW + (3.0V x 150mA) 150mA + 20A IOUT(MAX) < For example, if VIN = 5V, VOUT = 3V, and TA = 25C, IOUT(MAX) < 250mA. The output short-circuit protection threshold is set between 150mA and 300mA. If the output load current were to exceed 250mA or if the ambient temperature were to increase, the internal die temperature will increase. If the condition remained constant and the short-circuit protection were not to activate, there would be a potential damage hazard to LDO regulator since the thermal protection circuit will only activate after a short-circuit event occurs on the LDO regulator output. To determine the maximum input voltage for a given load current, refer to the following equation. This calculation accounts for the total power dissipation of the LDO regulator, including that caused by ground current. PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND) VIN(MAX) = VIN(MAX) = 4.33V 3200.2006.02.1.4 11 AAT3200 OmniPowerTM LDO Linear Regulator Higher input-to-output voltage differentials can be obtained with the AAT3200, while maintaining device functions in the thermal safe operating area. To accomplish this, the device thermal resistance must be reduced by increasing the heat sink area or by operating the LDO regulator in a duty-cycled mode. For example, an application requires VIN = 5.0V while VOUT = 3.0V at a 150mA load and TA = 85C. VIN is greater than 4.33V, which is the maximum safe continuous input level for VOUT = 3.0V at 150mA for TA = 85C. To maintain this high input voltage and output current level, the LDO regulator must be operated in a duty-cycled mode. Refer to the following calculation for duty-cycle operation: PD(MAX) is assumed to be 200mW. IGND IOUT VIN = 20A = 150mA = 5.0V PD(MAX) (VIN - VOUT)IOUT + (VIN x IGND) 200mW (5.0V - 3.0V)150mA + (5.0V x 20A) 3.5 Device Duty Cycle vs. VDROP (VOUT = 2.5V @ 25C) 3.5 Voltage Drop (V) 3 2.5 2 1.5 1 0.5 0 0 10 20 30 40 50 60 70 80 90 100 200mA 150mA Duty Cycle (%) Device Duty Cycle vs. VDROP (VOUT = 2.5V @ 50C) Voltage Drop (V) 3 2.5 2 1.5 1 0.5 0 0 10 20 30 40 50 60 70 80 100mA 200mA 150mA VOUT = 3.0V %DC = 100 %DC = 100 90 100 Duty Cycle (%) %DC = 66.6% Device Duty Cycle vs. VDROP For a 150mA output current and a 2.0V drop across the AAT3200 at an ambient temperature of 85C, the maximum on-time duty cycle for the device would be 66.6%. The following family of curves shows the safe operating area for duty-cycled operation from ambient room temperature to the maximum operating level.

The duty cycles for both output current levels must be taken into account. To do so, one would first need to calculate the power dissipation at the nominal continuous level, then factor in the addition power dissipation due to the short duration, high-current peaks. For example, a 3.0V system using a AAT3200IGV2.5-T1 operates at a continuous 100mA load current level and has short 150mA current peaks. The current peak occurs for 378s out of a 4.61ms period. It will be assumed the input voltage is 5.0V. First, the current duty cycle percentage must be calculated: % Peak Duty Cycle: X/100 = 378s/4.61ms % Peak Duty Cycle = 8.2% The LDO regulator will be under the 100mA load for 91.8% of the 4.61ms period and have 150mA peaks occurring for 8.2% of the time. Next, the continuous nominal power dissipation for the 100mA load should be determined then multiplied by the duty cycle to conclude the actual power dissipation over time. PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND) PD(100mA) = (4.2V - 3.0V)100mA + (4.2V x 20A) PD(100mA) = 120mW PD(91.8%D/C) = %DC x PD(100mA) PD(91.8%D/C) = 0.918 x 120mW PD(91.8%D/C) = 110.2mW The power dissipation for 100mA load occurring for 91.8% of the duty cycle will be 110.2mW. Now the power dissipation for the remaining 8.2% of the duty cycle at the 150mA load can be calculated: PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND) PD(150mA) = (4.2V - 3.0V)150mA + (4.2V x 20A) PD(150mA) = 180mW PD(8.2%D/C) = %DC x PD(150mA) PD(8.2%D/C) = 0.082 x 180mW PD(8.2%D/C) = 14.8mW The power dissipation for a 150mA load occurring for 8.2% of the duty cycle will be 14.8mW. Finally, the two power dissipation levels can be summed to determine the total power dissipation under the varied load. PD(total) = PD(100mA) + PD(150mA) PD(total) = 110.2mW + 14.8mW PD(total) = 125.0mW The maximum power dissipation for the AAT3200 operating at an ambient temperature of 85C is 200mW. The device in this example will have a total power dissipation of 125.0mW. This is well within the thermal limits for safe operation of the device. Printed Circuit Board Layout Recommendations In order to obtain the maximum performance from the AAT3200 LDO regulator, careful consideration should be given to the printed circuit board layout. If grounding connections are not properly made, power supply ripple rejection and LDO regulator transient response can be compromised. The LDO regulator external capacitors CIN and COUT should be connected as directly as possible to the ground pin of the LDO regulator. For maximum performance with the AAT3200, the ground pin connection should then be made directly back to the ground or common of the source power supply. If a direct ground return path is not possible due to printed circuit board layout limitations, the LDO ground pin should then be connected to the common ground plane in the application layout. 3200.2006.02.1.4 13 AAT3200 OmniPowerTM LDO Linear Regulator Ordering Information Output Voltage 1.8V 2.0V 2.3V 2.4V 2.5V 2.7V 2.8V 2.85V 3.0V 3.3V 3.5V 1.8V 2.0V 2.3V 2.4V 2.5V 2.7V 2.8V 3.0V 3.3V 3.5V Package SC59 SC59 SC59 SC59 SC59 SC59 SC59 SC59 SC59 SC59 SC59 SOT-89 SOT-89 SOT-89 SOT-89 SOT-89 SOT-89 SOT-89 SOT-89 SOT-89 SOT-89 Marking1 FAXYY Part Number (Tape and Reel)2 AAT3200IGY-1.8-T1 AAT3200IGY-2.0-T1 AAT3200IGY-2.3-T1 AAT3200IGY-2.4-T1 FRXYY AAT3200IGY-2.5-T1 AAT3200IGY-2.7-T1 EYXYY AAT3200IGY-2.8-T1 AAT3200IGY-2.85-T1 DGXYY DHXYY AAT3200IGY-3.0-T1 AAT3200IGY-3.3-T1 AAT3200IGY-3.5-T1 AAT3200IQY-1.8-T1 AAT3200IQY-2.0-T1 AAT3200IQY-2.3-T1 AAT3200IQY-2.4-T1 AAT3200IQY-2.5-T1 AAT3200IQY-2.7-T1 AAT3200IQY-2.8-T1 320030 320033 320035 AAT3200IQY-3.0-T1 AAT3200IQY-3.3-T1 AAT3200IQY-3.5-T1 All AnalogicTech products are offered in Pb-free packaging.
