Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's datasheet to confirm the exact switching frequency variant, as this parameter distinguishes it from other members of the LMR10515 family. Ensure the WSON-6 package dimensions match the target PCB layout constraints. Confirm RoHS compliance status through official documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a higher switching frequency than the 1.6 MHz variant is required to reduce passive component size. The 3 MHz operation allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the WSON-6 package for applications where board space is limited but thermal performance remains critical for sustained 1.5 A loads.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LMR10515 series of Simple Switcher regulators. It shares the same core architecture and pinout compatibility as other variants like the LMR10515XSD/NOPB, differing primarily in switching frequency specifications. The series is designed for cost-sensitive, space-constrained applications requiring reliable step-down regulation from single-cell lithium-ion sources.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR10515XSD/NOPB offers identical functionality with a 1.6 MHz switching frequency instead of 3 MHz. Both parts share the same WSON-6 package and electrical limits, allowing for potential substitution if the lower frequency meets the application's ripple and transient response requirements.
