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

Verify the specific ordering suffix 'Y5' corresponds to the SOT89-5 package configuration required for your design. Confirm that the '13' suffix aligns with your preferred tape and reel quantity specifications. Ensure compatibility with RoHS3 and halogen-free manufacturing standards if applicable to your regulatory requirements. Cross-reference the datasheet revision date against your bill of materials to ensure consistency with latest engineering changes.

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

Select this component when a fixed 2.5V rail is needed with high efficiency at moderate loads. The SOT89-5 package offers a balance between thermal dissipation and board space. Consider the 68µA quiescent current for battery-powered applications where standby consumption is critical. Verify that the input voltage remains above the minimum threshold while accounting for dropout voltage under full load conditions.

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

What is the purpose of the EN pin on the AP7361EA?

The EN pin serves as an active-high enable input. Setting it to a logic-high level turns the regulator on, while pulling it low disables the output.

Does the AP7361EA require a minimum load to remain stable?

No, the device is stable under no-load conditions without requiring a minimum load current or additional external components beyond the recommended capacitors.
