Check for any recent product change notifications that may affect marking or physical dimensions.

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

Select this component when a fixed 2.5V rail is required with up to 600mA load capacity. The SOT25 package offers a compact footprint suitable for space-constrained designs. Consider the thermal resistance of the chosen PCB layout to ensure junction temperatures remain within safe limits under maximum power dissipation conditions. Verify that the input voltage source can support the required headroom above the 2.5V output.

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

This part belongs to the AP7365 family of low dropout regulators produced by Diodes Incorporated. The family includes adjustable versions and various fixed output voltages across multiple packages like SOT89 and SOT223. The datasheet indicates this series is not recommended for new designs, suggesting the AP7366 as a modern alternative for future projects requiring similar performance specifications.

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

The AP7366 is explicitly identified in the documentation as the recommended replacement for new designs. Verify if the AP7366-25W5-7 meets all electrical and mechanical requirements before substitution.

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

What is the function of the EN pin on the AP7365-25WG-7?

The EN (Enable) pin controls the operation of the regulator. Setting the pin to a logic high level turns the device on, while pulling it low turns the device off.

Is an external feedback resistor network required for this part?

No, the AP7365-25WG-7 is a fixed-output version. It does not require external resistors to set the voltage, unlike the adjustable variants of the AP7365 series.

How does the device protect against overheating?

The device includes thermal shutdown protection that disables the output when the junction temperature rises to approximately +145°C. The output re-enables when the temperature drops to approximately +130°C.
