AP7347EQ-115FDCWR-7R

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

The AP7347EQ-115FDCWR-7R is a 500mA low-dropout regulator with a fixed 1.15V output, housed in a U-DFN2020-6 (SWP) package. It operates within a 1.7V to 5.5V input range and delivers ±1% output voltage accuracy across the -40°C to +125°C temperature spectrum. The device features 75dB ripple rejection at 1kHz and 60µVrms output noise from 10Hz to 100kHz. Quiescent current is 75µA, and it includes an enable pin, active output discharge, power-good indicator, and thermal/short-circuit protection.
