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

Verify the specific package type SOT89-5 and the fixed 1.2V output configuration when sourcing. Confirm that the ordering suffix -13 corresponds to the required tape and reel packaging format. Ensure compatibility with RoHS 3 and halogen-free manufacturing standards required for the target assembly process.

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

Select this component for designs requiring a fixed 1.2V rail from a 2.2V to 6.0V source. Consider the 600mV dropout voltage at 1A load to ensure sufficient headroom between input and output voltages. Evaluate thermal dissipation requirements based on the SOT89-5 package thermal resistance and expected ambient operating temperatures.

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

Does the AP7361EA-12Y5-13 support adjustable output voltages?

No, the '12' in the part number indicates a fixed 1.2V output. Adjustable versions are available with a blank designation in the voltage slot.

What is the minimum input voltage required for proper regulation?

The device requires a minimum input voltage of 2.2V. Additionally, the input must exceed the output voltage by at least the dropout voltage (typically 600mV at 1A) to maintain regulation.
