AP7347E-115FGECW-13A

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

The AP7347E-115FGECW-13A is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 1.15V output voltage and housed in a V-DFN3030-8/SWP (Type UX) package. 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 with a tolerance of ±1% and achieves a ripple rejection ratio of 75dB at 1kHz. It maintains low output noise of 60µVrms from 10Hz to 100kHz and draws a quiescent current as low as 75µA.

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

Verify the specific ordering suffix FGECW-13A to confirm the V-DFN3030-8/SWP package type and tape-and-reel packing quantity. Ensure the required 1.15V fixed output aligns with system design specifications before procurement. Confirm compliance with RoHS and halogen-free requirements if mandated by project standards.

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

Select this component when a stable 1.15V rail is required for noise-sensitive loads. The V-DFN3030-8/SWP package offers higher thermal dissipation compared to smaller footprints. Verify that the application benefits from the integrated power-good signal for system sequencing or status monitoring.

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

This part belongs to the AP7347E series, which is designed for high PSRR and low noise performance. Unlike the AP7347DQ, the AP7347E includes a dedicated power-good pin. The series supports both fixed and adjustable output voltages across various compact packages suitable for portable and industrial electronics.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

AP7347E-115FDCW-7R: Identical electrical specifications but utilizes the U-DFN2020-6 package instead of the V-DFN3030-8/SWP.

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

How does the power-good pin function?

The PG pin is an open-drain output that goes high-impedance when VOUT exceeds the threshold and pulls low when VOUT drops below the threshold or the device is disabled.

What is the recommended output capacitor configuration?

A minimum 1µF ceramic output capacitor is recommended for stability. The device remains stable with capacitance values ranging from 4.7µF to 100µF depending on ESR characteristics.
