AP7347E-17FDCWR-7R

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

The AP7347E-17FDCWR-7R is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 1.7V output voltage and housed in the U-DFN2020-6 (SWP) package with code FDCWR. It operates within an input voltage range of 1.7V to 5.5V and guarantees a continuous output current of 500mA. The device provides high output accuracy of ±1%, achieves a ripple rejection of 75dB at 1kHz, and maintains a low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is specified as low as 75µA.
