AP7344D-1815RH4-7

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

The AP7344D-1815RH4-7 is a dual-channel low-dropout regulator manufactured by Diodes Incorporated. It provides fixed output voltages of 1.8V on Channel 1 and 1.5V on Channel 2, with each channel capable of delivering up to 300mA. The device operates within an input voltage range of 1.7V to 5.25V and features ±1% output accuracy at +25°C. Key electrical characteristics include a typical ripple rejection of 75dB at 1kHz, low output noise of 60µVrms (10Hz to 100kHz), and a quiescent current as low as 50µA. It utilizes the X2-DFN1612-8 package.
