AP7366EA-18W5-7

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

The AP7366EA-18W5-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a regulated 1.8V output with a maximum continuous current of 600mA. The device operates within an input voltage range of 2.2V to 6V and maintains a typical quiescent current of 60µA. Key electrical characteristics include a typical power supply rejection ratio (PSRR) of 75dB at 1kHz, a fast start-up time of 150µs, and a line regulation of 0.01%/V. The unit is housed in a SOT-25-5 surface-mount package.
