Procurement Notes

Verify the specific suffix QDBVRQ1 matches the required automotive grade and package configuration. Confirm that the fixed 1.8 V output aligns with circuit design requirements. Ensure compatibility with the target PCB footprint for the SOT-23-6 package. Check for any specific handling or storage constraints related to moisture sensitivity level as indicated in the datasheet.

Selection Notes

Select this component when a stable, low-drift voltage reference is needed for automotive environments. It is suitable for designs requiring higher load current capability compared to nanoampere references. Consider the SOT-23-6 package size for space-constrained layouts. Evaluate the 15 ppm/°C drift against the system's total error budget to ensure sufficient precision for the application.
