AP7361EA-10FGE-7

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

The AP7361EA-10FGE-7 is a fixed-output linear regulator providing 1.0V at 1A maximum output current. It operates with an input voltage range of 2.2V to 6.0V and features ultra-low dropout performance, typically 840mV at full load. The device includes an enable pin for power control and maintains a typical quiescent current of 68µA. It offers high power supply rejection ratio of 75dB at 1kHz and incorporates foldback short-circuit protection limiting current to 400mA. Thermal shutdown activates at approximately 150°C junction temperature.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix FGE corresponds to the U-DFN3030-8 (Type E) package configuration required for your PCB layout. Confirm that the 1.0V fixed output matches the target rail voltage, as adjustable variants exist within the same family. Ensure the design accounts for the 1700mW power dissipation limit in this package type under maximum ambient temperature conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a stable 1.0V rail is required from a 2.2V to 6.0V source with low ground current consumption. The U-DFN3030-8 package is suitable for space-constrained designs requiring effective thermal dissipation through the exposed pad. Consider the 68µA quiescent current impact on battery life for portable applications compared to switching regulators.
