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

Verify that the specific part number matches the required SOT223R package configuration. Confirm the fixed 3.3V output specification aligns with the target circuit design. Ensure the ordering suffix corresponds to tape and reel packaging requirements. Cross-reference the manufacturer's datasheet for any recent revisions or environmental compliance updates before finalizing procurement.

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

Select this component when a fixed 3.3V rail is required with up to 1A capacity. The SOT223R package offers a compact footprint suitable for space-constrained designs. Consider the 500mV dropout voltage at full load to ensure sufficient input-to-output headroom. Verify that the operating temperature range meets the environmental demands of the application.

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

This component belongs to the AP7361 family of low dropout regulators designed for low to medium power applications. The series provides both adjustable and fixed output options across various packages. The AP7361-33ER-13 specifically utilizes the SOT223R variant, which lacks the adjustable mode feature found in other package types within the same family.
