NCV8502 Series Micropower 150 mA LDO Linear Regulators with DELAY, Adjustable RESET, and Monitor FLAG
The NCV8502 is a family of precision micropower voltage regulators. Their output current capability is 150 mA. The family has output voltage options for adjustable, 2.5 V, 3.3 V, 5.0 V, 8.0 V, and 10 V. The output voltage is accurate within 2.0% with a maximum dropout voltage of 0.6 V at 150 mA. Low quiescent current is a feature drawing only 90 mA with a 100 mA load. This part is ideal for any and all battery operated microprocessor equipment. Microprocessor control logic includes an active RESET (with DELAY), and a FLAG monitor which can be used to provide an early warning signal to the microprocessor of a potential impending RESET signal. The use of the FLAG monitor allows the microprocessor to finish any signal processing before the RESET shuts the microprocessor down. The active RESET circuit operates correctly at an output voltage as low as 1.0 V. The RESET function is activated during the power up sequence or during normal operation if the output voltage drops outside the regulation limits. The reset threshold voltage can be decreased by the connection of external resistor divider to RADJ lead. The regulator is protected against reverse battery, short circuit, and thermal overload conditions. The device can withstand load dump transients making it suitable for use in automotive environments. The device has also been optimized for EMC conditions.

CIRCUIT DESCRIPTION REGULATOR CONTROL FUNCTIONS The NCV8502 contains the microprocessor compatible control function RESET (Figure 12). 1. During Power Up (once the regulation threshold has been verified). 2. After a reset event has occurred and the device is back in regulation. The DELAY capacitor is discharged when the regulation (RESET threshold) has been violated. This is a latched incident. The capacitor will fully discharge and wait for the device to regulate before going through the delay time event again.
FLAG/Monitor Function
VIN RESET Threshold DELAY Threshold (VDT)
VOUT DELAY RESET Td Td
Figure 12. Reset and Delay Circuit Wave Forms RESET Function
A RESET signal (low voltage) is generated as the IC powers up until VOUT is within 6.0% of the regulated output voltage, or when VOUT drops out of regulation,and is lower than 8.0% below the regulated output voltage. Hysteresis is included in the function to minimize oscillations. The RESET output is an open collector NPN transistor, controlled by a low voltage detection circuit. The circuit is functionally independent of the rest of the IC thereby guaranteeing that the RESET signal is valid for VOUT as low as 1.0 V.
Adjustable Reset Function
An on-chip comparator is provided to perform an early warning to the microprocessor of a possible reset signal. The reset signal typically turns the microprocessor off instantaneously. This can cause unpredictable results with the microprocessor. The signal received from the FLAG pin will allow the microprocessor time to complete its present task before shutting down. This function is performed by a comparator referenced to the bandgap reference. The actual trip point can be programmed externally using a resistor divider to the input monitor (MON) (Figure 14). The typical threshold is 1.20 V on the MON pin.
VBAT VIN MON VOUT NCV8502 FLAG COUT I/O RESET VCC mP
The reset threshold can be made lower by connecting an external resistor divider to the RADJ lead from the VOUT lead, as displayed in Figure 13. This lead is grounded to select the default value of 4.6 V.

Figure 18. Test and Application Circuit Showing Output Compensation Figure 16. Additional Output Current Adding Capability
Figure 16 shows how the adjustable version of parts can be used with an external pass transistor for additional current capability. The setup as shown will provide greater than 1 Amp of output current. FLAG MONITOR Figure 17 shows the FLAG Monitor waveforms as a result of the circuit depicted in Figure 14. As the output voltage falls (VOUT), the Monitor threshold is crossed. This causes the voltage on the FLAG output to go low sending a warning signal to the microprocessor that a RESET signal may occur in a short period of time. TWARNING is the time the microprocessor has to complete the function it is currently working on and get ready for the RESET shutdown signal.
VOUT
SETTING THE DELAY TIME The delay time is controlled by the Reset Delay Low Voltage, Delay Switching Threshold, and the Delay Charge Current. The delay follows the equation:
tDELAY + [CDELAY(Vdt * Reset Delay Low Voltage)] Delay Charge Current
Example: Using CDELAY = 33 nF. Assume reset Delay Low Voltage = 0. Use the typical value for Vdt = 1.8 V. Use the typical value for Delay Charge Current = 2.5 mA.
tDELAY + [33 nF(1.8 * 0)] + 23.8 ms 2.5 mA
MON FLAG Monitor Ref. Voltage
STABILITY CONSIDERATIONS The output or compensation capacitor helps determine three main characteristics of a linear regulator: start-up delay, load transient response and loop stability. The capacitor value and type should be based on cost, availability, size and temperature constraints. The value for the output capacitor COUT shown in Figure 18 should work for most applications, however it is not necessarily the optimized solution.

Thermal Resistance, Junction to Ambient, RqJA, (C/W)
CALCULATING POWER DISSIPATION IN A SINGLE OUTPUT LINEAR REGULATOR The maximum power dissipation for a single output regulator (Figure 19) is:
PD(max) + [VIN(max) * VOUT(min)] IOUT(max) ) VIN(max)IQ
(eq. 1)
100 90 80 70 60 50 40 0 200 400 600 Copper Area (mm2) 800
where: VIN(max) is the maximum input voltage, VOUT(min) is the minimum output voltage, IOUT(max) is the maximum output current for the application, and IQ is the quiescent current the regulator consumes at IOUT(max). Once the value of PD(max) is known, the maximum permissible value of RqJA can be calculated:
T RQJA + 150C * A PD
(eq. 2)
Figure 20. 16 Lead SOW (Exposed Pad), qJA as a Function of the Pad Copper Area (2 oz. Cu Thickness), Board Material = 0.0625, G-10/R-4
The value of RqJA can then be compared with those in the package section of the data sheet. Those packages with RqJA's less than the calculated value in equation 2 will keep the die temperature below 150C. In some cases, none of the packages will be sufficient to dissipate the heat generated by the IC, and an external heatsink will be required.
IIN VIN SMART REGULATOR(R) IOUT VOUT
HEAT SINKS A heat sink effectively increases the surface area of the package to improve the flow of heat away from the IC and into the surrounding air. Each material in the heat flow path between the IC and the outside environment will have a thermal resistance. Like series electrical resistances, these resistances are summed to determine the value of RqJA:
RqJA + RqJC ) RqCS ) RqSA

Control Features IQ
Figure 19. Single Output Regulator with Key Performance Parameters Labeled
where: RqJC = the junction-to-case thermal resistance, RqCS = the case-to-heatsink thermal resistance, and RqSA = the heatsink-to-ambient thermal resistance. RqJC appears in the package section of the data sheet. Like RqJA, it too is a function of package type. RqCS and RqSA are functions of the package type, heatsink and the interface between them. These values appear in heat sink data sheets of heat sink manufacturers.
