Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'C' against the official datasheet to confirm it denotes the standard commercial grade variant rather than a specialized industrial or automotive qualification. Ensure the ordering part number matches the exact tape-and-reel quantity specified by the manufacturer to avoid packaging discrepancies during procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for moderate current applications up to 1.25A. The 1 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the input voltage does not exceed the 50V maximum rating and that the thermal performance of the WSON-10 package meets the application's heat dissipation requirements.
