AP7387Q-36FDCW-7

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

The AP7387Q-36FDCW-7 is a fixed-output automotive compliant ultra-low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 3.6V with a maximum output current capability of 150mA. The device operates within an input voltage range of 5V to 60V and maintains high output voltage accuracy of ±2%. Key electrical characteristics include a typical quiescent current of 2µA, a power supply rejection ratio of 70dB at 1kHz, and a typical dropout voltage of 1100mV at full load. It is housed in a U-DFN2020-6 (SWP) package.
