- Embedded control circuits with variable voltage demands
Procurement Notes
Verify the specific suffix codes on the ordering information to confirm the exact packaging type, such as tape and reel quantities, and ensure compliance with RoHS standards. Confirm the thermal performance characteristics relative to your PCB layout and ambient operating temperature conditions before finalizing procurement decisions.
Selection Notes
Select this component when a low-cost, adjustable linear regulator is required for currents up to 500 mA. Ensure the input voltage remains within the 2.5 V to 16 V range and that the desired output voltage falls between 0.8 V and 12 V. Consider the thermal dissipation capabilities of the 6-DFN package for your specific application environment.
Part Context
This part belongs to the LDFM series of fast, very low drop linear regulators from STMicroelectronics. The series includes both fixed and adjustable output variants, designed to provide reliable voltage regulation in space-constrained applications. The LDFMPVR specifically utilizes the adjustable output option within this family.
Replacement Considerations
Consult official STMicroelectronics documentation for direct pin-to-pin replacements or functional equivalents within the LDFM series. Verify that any substitute component matches the input voltage range, output current capacity, and package dimensions to ensure compatibility.
