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

Verify the specific ordering suffix 'D' corresponds to the TO252 package configuration required for your design. Confirm that the fixed 2.8V output aligns with your system's voltage requirements. Ensure compliance with RoHS and halogen-free specifications if mandated by your manufacturing standards. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match your schematic.

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

Select this component when a fixed 2.8V rail is needed with high current capability up to 1A. The TO252 package offers robust thermal dissipation for higher power applications compared to smaller footprints. Consider the 500mV dropout voltage to ensure sufficient headroom between input and output voltages during operation. Verify that the external capacitor values meet stability requirements for transient response.

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

This part belongs to the AP7361 family of low dropout regulators designed for low-to-medium power applications. The series includes both adjustable and fixed output variants across multiple packages such as SOT89-5, SO-8EP, and U-DFN3030-8.
