AP7375Q-18FDCW-7

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

The AP7375Q-18FDCW-7 is a wide input voltage range (45V), low quiescent current (2.1µA) automotive compliant ultra-low dropout linear regulator providing 300mA load current. It features an enable pin accepting up to 45V, fast transient response without overshoot during startup or short-circuit recovery, and integrated short-circuit and thermal shutdown protection. The device offers fixed output voltages including 1.8V with high accuracy of ±2% and high PSRR of 85dB at 1kHz. It is available in SOT89, SO-8EP, SOT25, and U-DFN2020-6 packages.

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

Verify the specific package code FDCW corresponds to the U-DFN2020-6 (SWP) Type UXC footprint for PCB layout compatibility. Confirm AEC-Q100 qualification and PPAP capability requirements are met for the target automotive application. Ensure EN pin logic levels align with system control signals before finalizing procurement specifications.

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

Select this component for applications requiring high input voltage tolerance up to 45V and low standby power consumption. The U-DFN2020-6 package provides compact surface-mount integration with exposed pad thermal dissipation. Verify that the required 1.8V output matches the fixed voltage option available in this series. Consider the 300mA maximum output current capability against peak load demands.
