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

Verify the specific suffix D4 corresponds to the TO252-4 package type required for your design. Confirm that the 50 suffix matches the necessary 5.0V fixed output voltage. Ensure the Q designation aligns with automotive compliance requirements if applicable to your project specifications.

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

Select this component when a low dropout voltage and high input voltage tolerance are required for automotive power distribution. The TO252-4 package offers superior thermal dissipation compared to smaller surface-mount options. Consider the 2.5µA quiescent current for battery-powered systems requiring minimal standby drain.

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

This part belongs to the AP7583Q/AQ series of wide-input-voltage LDO regulators designed specifically for automotive applications. The series includes adjustable and fixed voltage variants across multiple packages including MSOP-8EP, W-DFN2020-6, and TO252-4. All variants share core electrical characteristics but differ in pinout and thermal performance based on the selected package.
