AP7361-12FGE-7

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

The AP7361-12FGE-7 is a fixed-output linear regulator providing 1.2V at up to 1A output current, housed in an 8-pin U-DFN3030 package with exposed pad. It operates from a 2.2V to 6V input range with a typical dropout voltage of 200mV at 300mA and 500mV at 1A. The device features a low quiescent current of 70µA, high power supply rejection ratio (PSRR) of 65dB at 1kHz, and precise voltage regulation accuracy within ±1%. Integrated protections include current limiting, thermal shutdown, and short-circuit protection.

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

Verify that the component matches the specific 1.2V fixed output variant and the U-DFN3030-8 package configuration. Confirm compliance with RoHS and lead-free requirements as specified by Diodes Incorporated. Ensure the ordering suffix corresponds to tape and reel packaging if required for automated assembly processes.

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

Select this regulator when a stable 1.2V rail is needed with minimal voltage drop across the input-output differential. Consider the thermal resistance of the U-DFN3030-8 package for adequate heat dissipation at maximum load currents. Verify that the application does not require adjustable output settings, as this part is fixed-mode only.
