AP7361-28ER-13

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

The AP7361-28ER-13 is a fixed-output linear regulator manufactured by Diodes Incorporated, providing a stable 2.8V output with a maximum continuous current of 1A. 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, short-circuit protection, and thermal shutdown circuitry for fault management. It is housed in the SOT-223R surface-mount package and is rated 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 suffix ER-13 corresponds to the SOT-223R package and tape-and-reel packaging configuration. Confirm the fixed 2.8V output rating matches the design requirement. 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 2.8V rail is needed with high current capability up to 1A. The SOT-223R package offers a balance of thermal dissipation and footprint size. Consider the 70µA quiescent current for battery life optimization. Verify input voltage headroom to maintain regulation within the specified dropout limits.

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

This part belongs to the AP7361 family of 1A low dropout regulators from Diodes Incorporated. The series includes both adjustable and fixed output variants available in multiple packages such as U-DFN3030-8, SOT89-5, TO252, and SO-8EP. The AP7361-28ER-13 specifically denotes the fixed 2.8V version in the SOT-223R package.

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

AP7361C-28ER-13 is a recommended replacement for new designs, as the original AP7361 series is marked not recommended for new design.
