AP7344-3028RH4-7

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

The AP7344-3028RH4-7 is a dual low-dropout regulator from Diodes Incorporated, packaged in an X2-DFN1612-8 format. It provides two independent fixed output channels: Channel 1 delivers 3.0V and Channel 2 delivers 2.8V. The device guarantees a continuous output current of 300mA per channel with ±1% output voltage accuracy at +25°C. Operating within a wide input voltage range of 1.7V to 5.25V, it features a typical ripple rejection of 75dB at 1kHz and a low output noise of 60µVrms across the 10Hz to 100kHz bandwidth. Quiescent current is specified as low as 50µA.
