Overview

The NCP731 device is based on unique combination of features – very low noise, low quiescent current, fast transient response and high input and output voltage ranges. The NCP731 LDO regulator designed for up to 38 V input voltage and 150 mA output current. Very low noise (8 µVRMS) makes this device an ideal solution for applications where clean voltage rails are critical for system performance (power operational amplifiers, analog-to-digital / digital to-analog converters and other precision analog circuitry). The device (version B) implements power good circuit (PG) which indicates that output voltage is in regulation. This signal could be used for power sequencing or as a microcontroller reset. Internal short circuit and over temperature protections saves the device against overload conditions.
