AP7347EQ-30FDCW-7R

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

The AP7347EQ-30FDCW-7R is a fixed-output low-dropout regulator manufactured by Diodes Incorporated, delivering a precise 3.0V output with ±1% accuracy. It supports up to 500mA of guaranteed output current within an input voltage range of 1.7V to 5.5V. The device features a 75dB ripple rejection at 1kHz and a low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is maintained at a maximum of 75µA. It includes a power-good indicator, active output discharge, and operates reliably across a temperature range of -40°C to +125°C.

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

• High output-voltage accuracy of ±1% ensures stable power delivery for sensitive automotive loads.
• Integrated power-good (PG) open-drain output enables supply monitoring and sequencing functions.
• Active output discharge automatically pulls the output low when disabled to ensure known system states.
• Built-in thermal shutdown and foldback short-circuit protection safeguard against overheating and overcurrent conditions.

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

• Automotive ADAS load point applications
• Infotainment power supplies
• Automotive RF subsystems
• Automotive wireless communication systems

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

Verify that the specific suffix FDCWR indicates the U-DFN2020-6 package variant required for your design. Confirm AEC-Q100 qualification status if automotive production part approval process compliance is mandatory. Ensure the ordering code matches the exact 3.0V fixed output requirement rather than adjustable versions.

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

Select this component when designing noise-sensitive automotive circuits requiring high PSRR and low quiescent current. The 3.0V fixed output eliminates external resistor networks needed for adjustable versions. Verify that the U-DFN2020-6 package footprint aligns with PCB layout constraints and thermal dissipation requirements for the expected load current.
