AP7347E-25FDCW-7R

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

The AP7347E-25FDCW-7R is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 2.5V output voltage and housed in a U-DFN2020-6 (SWP) package with code FDCW. It supports an input voltage range of 1.7V to 5.5V and guarantees a continuous output current of 500mA. The device provides high output accuracy of ±1%, a ripple rejection of 75dB at 1kHz, and low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is as low as 75µA, and it includes a power-good indicator, active output discharge, and thermal shutdown protection.
