AP7347E-50FDCW-7R

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

The AP7347E-50FDCW-7R is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 5.0V output voltage and housed in a U-DFN2020-6 (SWP) package with code FDCW. It operates within an input voltage range of 1.7V to 5.5V and guarantees a continuous output current of 500mA. The device provides ±1% output voltage accuracy and includes a power-good indicator for supply monitoring. Key electrical characteristics include a ripple rejection of 75dB at 1kHz, low output noise of 60µVrms from 10Hz to 100kHz, and a quiescent current as low as 75µA.

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

Verify that the component matches the specified U-DFN2020-6 (SWP) package type and the fixed 5.0V output designation. Confirm the presence of the power-good feature and ensure the ordering suffix corresponds to the tape and reel packing format. Cross-reference the manufacturer part number against official Diodes Incorporated documentation to validate authenticity and revision status before procurement.

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

Select this regulator for designs requiring high power supply rejection and low noise performance in compact form factors. Ensure the input voltage remains within the 1.7V to 5.5V range and verify thermal dissipation capabilities given the small package size. Consider the need for external capacitors to maintain stability and evaluate the power-good pin requirements for system sequencing logic.
