AP7347EQ-11FDCWR-7R

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

The AP7347EQ-11FDCWR-7R is a low-dropout regulator manufactured by Diodes Incorporated, featuring an 1.1V fixed output voltage and housed in a U-DFN2020-6 (SWP) package with code FDCWR. It supports an input voltage range of 1.7V to 5.5V and guarantees a continuous output current of 500mA. The device provides ±1% output voltage accuracy, 75dB ripple rejection at 1kHz, and 60µVrms output noise from 10Hz to 100kHz. Quiescent current is as low as 75µA, and it includes power-good indication, active output discharge, and thermal/short-circuit protection.
