NCP400

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.
