AP7347E-115FDCW-7R

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

The AP7347E-115FDCW-7R is a low dropout regulator manufactured by Diodes Incorporated, featuring high output voltage accuracy and low noise. It operates within an input voltage range of 1.7V to 5.5V and provides a guaranteed output current of 500mA. The device delivers a fixed output voltage of 1.15V with ±1% accuracy. Key electrical parameters include a ripple rejection of 75dB at 1kHz, an output noise of 60µVrms from 10Hz to 100kHz, and a quiescent current as low as 75µA. It incorporates a power-good indicator and active output discharge.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix '7R' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the U-DFN2020-6 package code matches the footprint constraints of the target PCB design. Ensure the fixed 1.15V output aligns precisely with the load requirements, as adjustable versions utilize different suffixes.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for designs requiring precise 1.15V regulation with minimal noise in compact spaces. The U-DFN2020-6 package offers high power density suitable for space-constrained layouts. Consider the 75µA quiescent current for standby efficiency and verify that the 500mA output capability meets peak load demands without exceeding thermal limits under maximum ambient conditions.
