AP7347EQ-10FGECW-13A

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

The AP7347EQ-10FGECW-13A is a 500mA low-dropout regulator with a fixed 1.0V output, packaged in V-DFN3030-8/SWP (Type UX). It operates within an input voltage range of 1.7V to 5.5V and maintains ±1% output accuracy across the -40°C to +125°C temperature range. The device features 75dB ripple rejection at 1kHz and 60µVrms output noise from 10Hz to 100kHz. Quiescent current is 75µA, and it includes power-good indication, active discharge, and thermal/short-circuit protection.

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

How does the power-good pin function?

The PG pin is an open-drain output that goes high-impedance when VOUT exceeds the threshold and pulls low when VOUT drops below the threshold or the device is disabled.

What happens during a short circuit?

Short-circuit protection triggers and clamps the output current to approximately 180mA to prevent damage from overheating.
