Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required thermal pad configuration and pinout compatibility for the target PCB layout. Cross-reference the RoHS compliance status with the latest datasheet revision to guarantee adherence to environmental regulations for the intended manufacturing process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring high input voltage tolerance up to 100V with moderate current demands around 600mA. The 8-PowerSOIC package offers a balance between thermal performance and board space efficiency compared to larger packages. Consider the fixed on-time control behavior for stability in applications where load transients are frequent and require rapid recovery without complex compensation networks.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM5017 family of high-voltage synchronous buck regulators. It shares architectural similarities with other devices in the series but differs in packaging and specific electrical tolerances. The MRE suffix denotes the PowerSOIC-8 package variant, distinguishing it from WSON or other footprint options available within the same functional family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM5017SDX/NOPB: Offers identical functionality in a WSON-8 package; verify thermal dissipation requirements and footprint differences. LM5017MR/NOPB: Same SOIC-8 package; confirm if any minor parameter variations exist between specific sub-revisions.
