AP7361C-28SP-13

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

The AP7361C-28SP-13 is a fixed-output linear regulator providing 2.8V at up to 1A output current, housed in an SO-8EP package with an enable pin. It operates within a 2.2V to 6.0V input range and delivers a typical dropout voltage of 340mV at full load. The device features a low quiescent current of 60µA and high power supply rejection ratio of 75dB at 1kHz. Integrated protections include current limiting at 1.5A, fold-back short circuit protection at 400mA, and thermal shutdown at 150°C.

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

Verify that the specific suffix 'SP' corresponds to the SO-8EP package variant when sourcing. Confirm the '13' packaging suffix matches the required tape and reel specifications for your assembly line. Ensure the component meets RoHS compliance standards if required by your manufacturing process. Cross-reference the manufacturer part number directly with official Diodes Incorporated documentation to avoid counterfeit parts.

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

Select this model when a fixed 2.8V rail is required with a maximum 1A load capability. The SO-8EP package offers higher power dissipation compared to smaller footprints, suitable for moderate thermal environments. Verify that the input voltage remains above 2.2V and consider the dropout characteristics relative to your minimum input supply. Ensure adequate PCB copper area is allocated for thermal management given the package's thermal resistance.
