AP7347E-12FDCWR-7R

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

The AP7347E-12FDCWR-7R is a fixed-output low dropout regulator manufactured by Diodes Incorporated, delivering a nominal 1.2V output with ±1% accuracy. It operates within an input voltage range of 1.7V to 5.5V and supports up to 500mA of guaranteed output current. The device features a 75dB ripple rejection at 1kHz and a low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is specified as low as 75µA. It includes a power-good indicator, active output discharge, and thermal shutdown protection, housed in a U-DFN2020-6 (SWP) package.
