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

Verify the specific package type matches the design requirements, as the AP7361C series spans multiple form factors including SOT89-5, U-DFN3030-8, and TO252. Confirm that the ordering suffix corresponds to the desired tape and reel quantity. Ensure the selected variant supports the required operating temperature range and complies with applicable environmental directives such as RoHS 3.

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

Select this component when a fixed 1.8V rail is needed with moderate current capability. The SO-8EP package offers improved thermal dissipation compared to smaller footprints. Consider the 60µA quiescent current for battery life calculations. Verify that the input voltage remains above the minimum threshold plus the dropout voltage across all operating conditions to ensure proper regulation.
