AP7361EA-12ER-13

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

The AP7361EA-12ER-13 is a fixed-output linear regulator from Diodes Incorporated, providing a stable 1.2V output at up to 1A load current. It operates within an input voltage range of 2.2V to 6.0V and features a typical dropout voltage of 780mV at full load. The device incorporates an enable pin for power management, with a typical quiescent current of 68µA. It includes built-in current limiting (1.5A) and thermal shutdown protection. The component is housed in a SOT223R surface-mount package.
