NCP400 Datasheet, PDF (1/14 Pages) ON Semiconductor – 150 mA CMOS Low Iq Low-Dropout Voltage Regulator with Voltage Detector Output

NCP400
150 mA CMOS Low Iq
Low−Dropout Voltage
Regulator with Voltage
Detector Output
The NCP400 is an integration of a low−dropout regulator and a
voltage detector in a very small chip scale package. The voltage
regulator is capable of supplying 150 mA with a low dropout of 160 mV
at 100 mA. It contains a voltage reference unit, an error amplifier,
comparators, PMOS power transistor, current limit and thermal
shutdown protection circuits for the regulator portion.
A highly accurate voltage detector with hysteresis and an externally
programmable time delay generator are implemented to prevent
erratic system reset operation. It features complementary output with
active low reset function.
The NCP400 is designed to work with low cost ceramic capacitors
and requires only a small 1.0 mF capacitor at regulator output. Its low
quiescent current is ideal for battery powered applications.
