NCV8730

LDO Regulator, 150 mA, 38 V, 1 µA IQ, with PG

Overview

The NCV8730 device is based on unique combination of features −very low quiescent current, fast transient response and high input andoutput voltage ranges. The NCV8730 is CMOS LDO regulatordesigned for up to 38 V input voltage and 150 mA output current.Quiescent current of only 1 µA makes this device ideal solution forbattery− powered, always−on systems. Several fixed output voltageversions are available as well as the adjustable version.The device (version B) implements power good circuit (PG) whichindicates that output voltage is in regulation. This signal could be usedfor power sequencing or as a Microcontroller reset.Internal short circuit and over temperature protections saves thedevice against overload conditions.

Applications

MCU/analog power supply from higher voltage internal rail
Power supply for gate driver
