AP7361EA-18FGE-7

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

The AP7361EA-18FGE-7 is a fixed-output linear regulator from Diodes Incorporated, providing a stable 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 340mV at full load. The device incorporates an enable pin for power management and maintains a low quiescent current of approximately 68µA. It includes built-in thermal shutdown and current limiting protection. The component is housed in a U-DFN3030-8 (Type E) package with an exposed pad for thermal dissipation.
