AP7347E-29FGECW-13A

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

The AP7347E-29FGECW-13A is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a precise 2.9V output voltage. It operates within an input voltage range of 1.7V to 5.5V and guarantees a continuous output current of 500mA. The device features high power supply rejection ratio (PSRR) of 75dB at 1kHz and low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is specified as low as 75µA. It includes integrated thermal shutdown, short-circuit protection with fold-back current limiting, and an active output discharge function. The component is housed in a V-DFN3030-8/SWP package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated open-drain Power-Good indicator for supply monitoring and sequencing
• Active output discharge ensures known system startup states when disabled
• Fold-back current limit protects against overcurrent and overheating during short circuits
• Thermal shutdown circuitry disables the output at elevated junction temperatures

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

• Noise-sensitive equipment requiring stable power rails
• Servers and desktop computing systems
• Gaming consoles
• Camera modules

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

Verify that the specific ordering suffix FGECW corresponds to the V-DFN3030-8/SWP package type and the 13A packing designation indicates tape and reel packaging. Confirm the internal code matches the required 2.9V fixed output voltage configuration before finalizing procurement specifications.

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

Select this component for applications requiring a fixed 2.9V rail with high ripple rejection capabilities. Ensure the design accommodates the V-DFN3030-8/SWP footprint and utilizes adequate copper area on the exposed pad for thermal dissipation. Verify that the load transient requirements align with the stability characteristics provided for ceramic output capacitors.

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

This part belongs to the AP7347E series of 500mA high PSRR low noise LDOs. Unlike the automotive-grade AP7347DQ variant, the AP7347E focuses on general-purpose industrial and consumer electronics markets. It shares core electrical performance metrics but lacks AEC-Q100 qualification, making it suitable for non-automotive environments such as consumer electronics and IT infrastructure.

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

AP7347E-29FDCW-7R offers identical electrical specifications but utilizes the U-DFN2020-6 package instead of the V-DFN3030-8/SWP.
