AP7347E-105FDCW-7R

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

The AP7347E-105FDCW-7R is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 1.05V 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 high output accuracy of ±1%, a ripple rejection ratio of 75dB at 1kHz, and low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is specified as low as 75µA, and it includes a power-good indicator along with active output discharge functionality.

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

Verify the specific ordering suffix '7R' corresponds to tape and reel packaging containing 3000 units per carrier. Confirm that the 'FDCW' package code matches the required U-DFN2020-6 footprint for PCB layout compatibility. Ensure the fixed 1.05V output voltage meets the target circuit requirements before finalizing procurement specifications.

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

Select this component for designs requiring precise 1.05V regulation with minimal quiescent current consumption. The integrated power-good pin facilitates reliable system initialization sequences. Verify that the thermal dissipation capabilities of the U-DFN2020-6 package are sufficient for the expected ambient temperature and load conditions to prevent thermal shutdown.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the AP7347E series of low dropout regulators designed for noise-sensitive equipment. Unlike the AP7347DQ variant which lacks a power-good indicator, the AP7347E includes this feature for enhanced system control. The device utilizes a CMOS process to achieve low on-resistance and high power supply rejection ratios across its operating temperature range.
