AP7361C-10DR-13

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

The AP7361C-10DR-13 is a fixed-output linear regulator from Diodes Incorporated, providing a stable 1.0V 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 840mV at full load. The device incorporates an enable pin for power management, with a quiescent current of approximately 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)R surface-mount package.

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

Verify the specific ordering suffix DR corresponds to the TO252 (DPAK)R tape and reel packaging configuration. Confirm that the fixed 1.0V output variant matches the system requirements, as the AP7361C series also offers adjustable and other fixed voltage options. Ensure compatibility with RoHS3 and halogen-free manufacturing standards required by the target assembly process.

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

Select this component when a fixed 1.0V rail is required with high current capability in a compact surface-mount form factor. The TO252 (DPAK)R package provides adequate thermal dissipation for moderate power loads. Consider the 840mV dropout voltage at 1A when designing the input-to-output voltage differential. Verify that the application does not require the adjustable version or alternative packages like U-DFN3030-8 for space-constrained designs.

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

This part belongs to the AP7361C family of 1A low dropout regulators designed for low-to-medium power applications. The series supports both fixed and adjustable output voltages across various packages including SOT89-5, SOT223, and SO-8EP. The AP7361C distinguishes itself with an enable pin feature and high PSRR, making it suitable for consumer electronics and portable devices requiring efficient power management.

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

Direct substitutes within the same family include AP7361C-10D-13 (standard TO252 DPAK) or AP7361C-10SP-13 (SO-8EP). Cross-voltage variants such as AP7361C-12DR-13 (1.2V) are electrically similar but provide different output levels. Ensure any replacement maintains the TO252 (DPAK)R footprint if board space is constrained.
