Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix SDDAR corresponds to the HSOIC-8 package with tape and reel packaging. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact pinout and thermal pad configuration specified in the official datasheet.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when high input voltage tolerance up to 80 V is required alongside a compact 8-pin footprint. The adjustable frequency allows optimization for either efficiency or solution size. Consider the 40 µA quiescent current for battery-powered standby modes and verify that the 2 A output current meets the load requirements.
