AP7347E-33FGECW-13A

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

The AP7347E-33FGECW-13A is a fixed-output low dropout regulator manufactured by Diodes Incorporated, delivering a precise 3.3V output with a maximum guaranteed current of 500mA. It operates within an input voltage range of 1.7V to 5.5V and maintains ±1% output accuracy across the -40°C to +125°C temperature range. The device features a 75dB ripple rejection at 1kHz and a low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is limited to 75µA, and it includes power-good indication, active output discharge, and thermal shutdown protection.

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

Verify the package code FGECW corresponds to the V-DFN3030-8/SWP (Type UX) footprint during procurement. Confirm that the '13A' suffix indicates 13-inch tape and reel packaging. Ensure the ordering part number matches the required 3.3V fixed output configuration before finalizing purchase orders.

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

Select this component when designing circuits requiring high PSRR and low noise for sensitive analog or RF loads. The V-DFN3030-8 package provides superior thermal dissipation compared to smaller alternatives. Verify that the application load transient requirements align with the specified stability characteristics using ceramic capacitors.

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

This component belongs to the AP7347E series of high-performance LDO regulators designed for demanding consumer and industrial applications. Unlike the AP7347DQ which lacks a power-good pin, the AP7347E integrates PG functionality. The specific model utilizes the larger V-DFN3030-8 package to handle higher power densities while maintaining compact board space.
