AP7361-25ER-13

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

The AP7361-25ER-13 is a fixed-output linear regulator manufactured by Diodes Incorporated, providing a stable 2.5V output with a maximum continuous current of 1A. It operates within an input voltage range of 2.2V to 6V and features a typical dropout voltage of 500mV at full load. The device incorporates an enable pin for power control and maintains a low quiescent current of approximately 70µA. It is housed in the SOT223R surface-mount package and supports an ambient operating temperature range from -40°C to +85°C.

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

Verify that the component matches the specific SOT223R package configuration and the 2.5V fixed output designation. Confirm RoHS compliance and lead-free status requirements align with project specifications. Ensure the ordering suffix corresponds to tape and reel packaging if automated assembly is planned. Cross-reference datasheet revision DS33626 Rev. 11-3 for accurate electrical parameters.

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

Select this regulator when a fixed 2.5V rail is required with up to 1A load capability. The SOT223R package offers a balance between thermal dissipation and board space efficiency. Consider the 500mV dropout voltage to ensure sufficient headroom between input and output voltages. Verify that the application does not require adjustable output settings, as this variant is fixed.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the AP7361 family of ultra-low dropout linear regulators designed for low-to-medium power applications. The series includes both adjustable and fixed output variants across multiple packages such as U-DFN3030-8, SOT89-5, TO252, and SO-8EP. The AP7361-25ER-13 specifically denotes the 2.5V fixed version in the SOT223R package.
