AP7344D-2825RH4-7

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

The AP7344D-2825RH4-7 is a dual-channel low-dropout regulator manufactured by Diodes Incorporated. It provides fixed output voltages of 2.8V on Channel 1 and 2.5V on Channel 2, with a guaranteed continuous output current of 300mA per channel. The device operates within an input voltage range of 1.7V to 5.25V and maintains an output voltage accuracy of ±1% at +25°C. Key electrical characteristics include a typical ripple rejection ratio of 75dB at 1kHz, a low output noise of 60µVrms across the 10Hz to 100kHz bandwidth, and a quiescent current as low as 50µA. The component utilizes an X2-DFN1612-8 package.
