AP7347D-15FDZW-7B

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

The AP7347D-15FDZW-7B is a low-dropout regulator manufactured by Diodes Incorporated, featuring a fixed 1.5V output voltage and housed in a W-DFN2020-6 (SWP) package with an active discharge function. It operates within an input voltage range of 1.7V to 5.5V and guarantees a continuous output current of 500mA. The device maintains a voltage accuracy of ±1% across the operating temperature range of -40°C to +125°C. Key electrical characteristics include a ripple rejection ratio of 75dB at 1kHz, an output noise voltage of 60µVrms from 10Hz to 100kHz, and a quiescent current as low as 60µA.
