Overview

The NCP730 device is based on unique combination of features - very low quiescent current, fast transient response and high input and output voltage ranges. The NCP730 is CMOS LDO regulator designed for up to 38 V input voltage and 150 mA output current. Quiescent current of only 1 uA makes this device ideal solution for battery-powered, always-on systems. Several fixed output voltage versions are available as well as the adjustable version.The B-version device 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.
