NCP612, NCV612 100 mA CMOS Low Iq Voltage Regulator in an SC70-5
The NCP612/NCV612 series of fixed output linear regulators are designed for handheld communication equipment and portable battery powered applications which require low quiescent. The NCP612/NCV612 series features an ultra-low quiescent current of 40 mA. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, current limit, and temperature limit protection circuits. The NCP612/NCV612 has been designed to be used with low cost ceramic capacitors. The device is housed in the micro-miniature SC70-5 surface mount package. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.1, 3.3, 3.7, and 5.0 V.

DEFINITIONS
Load Regulation Line Regulation
The change in output voltage for a change in output current at a constant temperature.
Dropout Voltage
The input/output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 3.0% below its nominal. The junction temperature, load current, and minimum input supply requirements affect the dropout level.
Maximum Power Dissipation
The change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or by using pulse technique such that the average chip temperature is not significantly affected.
Line Transient Response
Typical over and undershoot response when input voltage is excited with a given slope.
Thermal Protection
The maximum total dissipation for which the regulator will operate within its specifications.
Quiescent Current
The quiescent current is the current which flows through the ground when the LDO operates without a load on its output: internal IC operation, bias, etc. When the LDO becomes loaded, this term is called the Ground current. It is actually the difference between the input current (measured through the LDO input pin) and the output current.
Internal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. When activated at typically 160C, the regulator turns off. This feature is provided to prevent failures from accidental overheating.
Maximum Package Power Dissipation
The maximum power package dissipation is the power dissipation level at which the junction temperature reaches its maximum operating value, i.e. 150C. Depending on the ambient power dissipation and thus the maximum available output current.

APPLICATIONS INFORMATION A typical application circuit for the NCP612/NCV612 is shown in Figure 1, front page.
Input Decoupling (C1)
Set external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible.
Thermal
A 1.0 mF capacitor either ceramic or tantalum is recommended and should be connected close to the NCP612/NCV612 package. Higher values and lower ESR will improve the overall line transient response. TDK capacitor: C2012X5R1C105K, or C1608X5R1A105K
Output Decoupling (C2)
The NCP612/NCV612 is a stable regulator and does not require any specific Equivalent Series Resistance (ESR) or a minimum output current. Capacitors exhibiting ESRs ranging from a few mW up to 5.0 W can thus safely be used. The minimum decoupling value is 1.0 mF and can be augmented to fulfill stringent load transient requirements. The regulator accepts ceramic chip capacitors as well as tantalum capacitors. Larger values improve noise rejection and load regulation transient response. TDK capacitor: C2012X5R1C105K, C1608X5R1A105K, or C3216X7R1C105K
Enable Operation
As power across the NCP612/NCV612 increases, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration on the PCB, the board material and also the ambient temperature effect the rate of temperature rise for the part. This is stating that when the NCP612/NCV612 has good thermal conductivity through the PCB, the junction temperature will be relatively low with high power dissipation applications. The maximum dissipation the package can handle is given by:
T *TA PD + J(max) RqJA
The enable pin will turn on the regulator when pulled high and turn off the regulator when pulled low. These limits of threshold are covered in the electrical specification section of this data sheet. If the enable is not used then the pin should be connected to Vin.
Hints
If junction temperature is not allowed above the maximum 125C, then the NCP612/NCV612 can dissipate up to 330 mW @ 25C. The power dissipated by the NCP612/NCV612 can be calculated from the following equation:
Ptot + [Vin * Ignd (Iout)] ) [Vin * Vout] * Iout
or
P ) Vout * Iout VinMAX + tot Ignd ) Iout
Please be sure the Vin and Gnd lines are sufficiently wide. When the impedance of these lines is high, there is a chance to pick up noise or cause the regulator to malfunction.
If an 100 mA output current is needed then the ground current from the data sheet is 40 mA. For an NCP612/NCV612 (3.0 V), the maximum input voltage will then be 6.0 V (Limited by maximum input voltage).
