AP7361C-18E-13

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

The AP7361C-18E-13 is a fixed-output linear regulator manufactured by Diodes Incorporated, providing a regulated 1.8V 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 570mV at full load. The device incorporates an enable pin for power control and maintains a low quiescent current of approximately 60µA. Built-in protections include current limiting at 1.5A and thermal shutdown at 150°C. It is housed in a SOT223 package.
