AP7375-50FDCW-7

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

The AP7375-50FDCW-7 is a fixed-output low-dropout linear regulator manufactured by Diodes Incorporated. It provides a regulated output voltage of 5.0V with a maximum load current capability of 300mA. The device supports a wide input voltage range from 3V to 45V and features a dedicated enable pin that accepts up to 45V. Key electrical characteristics include a typical quiescent current of 2.1μA, high power supply rejection ratio of 85dB at 1kHz, and excellent line and load regulation. The component is housed in a U-DFN2020-6 (SWP) package with wettable flanks.

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

Verify the specific suffix FDCW corresponds to the U-DFN2020-6 package with wettable flanks when sourcing. Confirm the -50 designation matches the required 5.0V output voltage for your circuit design. Ensure compatibility with the recommended ceramic output capacitor specifications to maintain stability. Check for automotive-grade alternatives if AEC-Q100 certification is required for your application environment.

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

Select this component when a wide input voltage range up to 45V is necessary alongside a fixed 5.0V output. The low quiescent current makes it suitable for battery-operated systems where standby power consumption must be minimized. Consider the U-DFN2020-6 package for compact designs requiring efficient thermal dissipation through the exposed pad. Verify that the 300mA output current meets the peak load requirements of the downstream circuitry.
