Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QMR' indicates automotive qualification (AEC-Q100) and SO-PowerPAD-8 packaging. Confirm the 'ADJ' designation matches the required adjustable output configuration. Ensure the 'NOPB' suffix denotes lead-free and RoHS compliance status prior to ordering to meet environmental standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 42 V and a continuous 1 A load are required. The fixed 500 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the SO-PowerPAD-8 package for thermal performance in space-constrained designs. Verify that the application environment meets the -40°C to +125°C operating temperature range specifications.
