AP7315Q-27W5-7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7315Q-27W5-7 is an automotive-compliant low dropout regulator manufactured by Diodes Incorporated. It provides a fixed 2.7V output with a maximum current of 150mA and operates within a 1.7V to 5.25V input range. The device features high power supply rejection ratio (PSRR) of 75dB at 1kHz, low output noise of 60µVrms from 10Hz to 100kHz, and a quiescent current as low as 35µA. It includes an enable pin for shutdown control but lacks an internal output discharge function. Qualified to AEC-Q100 Grade 1 standards, it supports PPAP documentation and operates across a temperature range of -40°C to +125°C.
