AP131-30WG-7

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

The AP131-30WG-7 is a fixed-output linear regulator providing 3.0V at up to 300mA in an SOT-25 package. It operates with an input voltage range of 2.7V to 5.5V and features a typical dropout voltage of 400mV at full load. The device draws approximately 50µA quiescent current and includes active-low shutdown functionality via the EN pin. Built-in protections include current limiting, thermal shutdown, and short-circuit fold-back.
