Power Management - Specialized Procurement Notes

Verify the specific suffix (+T) against your bill of materials, as it indicates reel packaging which may differ from cut tape availability. Confirm RoHS compliance status through official documentation before integration. Ensure the WLP-25 package footprint matches your PCB layout constraints. Check for any regional sales restrictions or limited supply notices associated with this component.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring multiple regulated outputs from a single inductor to minimize board space. It is appropriate for applications demanding wide input voltage ranges and high thermal performance. Consider the WLP-25 package size if space is constrained. Verify that the 150 mA current capability meets the peak load requirements of all connected rails simultaneously.
