150 mA CMOS Low Iq LDO Voltage Regulator with Voltage Detector Output

The NCP400 is a low-dropout regulator with integrated programmable delay's voltage detection function, which is designed for portable battery powered applications. This device is capable of supplying 150mA to output with a dropout of 160mV/100mA. Offers ultra-low quiescent current of 50uA(typ.) at full load and 0.25uA(typ.) when device is disabled. NCP400 contains a voltage reference unit, an error amplifier, comparators, PMOS power transistor, current limit and temperature limit protection circuits for the regulator portion.

The NCP400 has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of 1.0uF at regulator output. The device is housed in the Microbump-6 package.
