Procurement Notes

Verify the specific suffix 'A25' confirms the 2.5 V output variant when ordering. Ensure the DBVR package designation matches the required surface-mount footprint. Confirm automotive qualification status if the application requires AEC-Q100 compliance, as standard commercial versions may differ from qualified variants.

Selection Notes

Select this component when a fixed 2.5 V reference is needed with high accuracy and low power consumption. Compare against adjustable shunt references if variable output is required. Consider the SOT-23-5 package size constraints relative to available board space. Verify thermal performance requirements against the specified operating temperature range.
