AP7361-12E-13

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

The AP7361-12E-13 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated, providing a stable 1.2V output at up to 1A load current. It operates within an input voltage range of 2.2V to 6V and features a typical quiescent current of 70µA. The device incorporates built-in current limiting, thermal shutdown, and short-circuit protection. It is housed in the SOT223 surface-mount package and is designed for operation across an ambient temperature range of -40°C to +85°C.

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

Verify that the specific part number matches the required fixed 1.2V output configuration and SOT223 package style. Confirm compliance with RoHS and lead-free manufacturing standards as specified in the datasheet. Ensure the ordering suffix corresponds to tape and reel packaging if automated assembly is intended. Cross-reference the manufacturer's latest documentation for any potential design changes or obsolescence notices before finalizing procurement.

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

Select this component when a fixed 1.2V rail is required for low-to-medium power applications. The SOT223 package offers adequate thermal dissipation for moderate loads. Consider the 2.2V minimum input voltage constraint against the available supply rails. Evaluate the need for the enable pin functionality, noting that it may not be present in all package variants of the broader series.
