Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QDRRRQ1' against the manufacturer's official ordering guide to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure the procurement channel provides valid traceability documentation required for automotive-grade components. Cross-reference the datasheet revision date to confirm compatibility with current design specifications before finalizing orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for automotive environments requiring a 36 V input tolerance and 3 A load capacity. The fixed 400 kHz frequency aids in EMI filtering compared to higher-frequency alternatives. Consider the thermal performance of the WSON-12 package relative to the PCB copper area, as heat dissipation relies heavily on board layout rather than external heatsinks.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the SIMPLE SWITCHER family, designed for compact power solutions. It integrates power switches and control logic into a single monolithic IC. The Q1 suffix indicates it meets rigorous automotive quality and reliability standards, distinguishing it from standard commercial-grade counterparts in the same series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-to-pin replacements within the same series include LMR23630DRRR and LMR23630ADDAG4. Verify that alternative parts meet the specific AEC-Q100 qualification requirements if automotive compliance is mandatory for the application.
