AP7361C-12D-13

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

The AP7361C-12D-13 is a fixed-output linear regulator from 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 6.0V and features a typical dropout voltage of 540mV at full load. The device incorporates an enable pin for power management, achieving a low quiescent current of 60µA. Built-in protections include current limiting at 1.5A, fold-back short circuit protection, and thermal shutdown at 150°C. It is housed in a TO252 (DPAK) surface-mount package.

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

Verify the specific suffix 'D' corresponds to the TO252 (DPAK) package configuration required for your PCB layout. Confirm that the -13 packaging suffix matches your reel or cut tape requirements. Ensure the 1.2V fixed output aligns with your target rail voltage before finalizing procurement specifications.

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

Select this component when a fixed 1.2V rail is needed with high current capability up to 1A. The TO252 package offers higher power dissipation compared to smaller packages, suitable for moderate thermal loads. Verify that the input voltage remains within the 2.2V to 6.0V range and that the application benefits from the integrated enable feature for power sequencing.

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

This part belongs to the AP7361C series, which includes both adjustable and fixed-output variants. The series is designed for low-to-medium power applications requiring high efficiency and low noise. Other members of the family offer different output voltages and package options such as SOT89-5, SO-8EP, and U-DFN3030-8.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Compatible substitutes within the same family include AP7361C-12E-13 (SOT223 package) and AP7361C-12SP-13 (SO-8EP package). These alternatives share identical electrical characteristics but differ in physical footprint and thermal dissipation capabilities due to package variations.
