Procurement Notes

Verify the specific suffix 'DBZT' corresponds to the SOT-23-3 package and tape-and-reel delivery format as per the official datasheet. Confirm that the 'A' grade designation aligns with the required ±0.1% initial accuracy specifications for your design. Ensure compatibility with the specified operating temperature range and thermal management requirements during integration.

Selection Notes

Select this component when a fixed 2.5V reference with exceptional accuracy and low drift is required. Consider its small SOT-23-3 package for space-constrained designs. Evaluate the 80µA quiescent current against system power budgets. Verify that the input voltage range meets the supply constraints of the target application environment.

Part Context

Part of the REF29xx family of shunt voltage references, designed for general-purpose precision applications. The REF2920 variant specifically provides a 2.5V output, distinguishing it from other members offering different fixed voltages like 2.0V or 3.0V. It shares common architectural features such as bandgap regulation but differs in output set-point and specific grading options available within the series.

Replacement Considerations

Check for direct pin-compatible alternatives from the same manufacturer family with matching output voltage and package type. Verify if other manufacturers offer equivalent 2.5V references with similar accuracy and temperature coefficient specifications. Ensure any substitute maintains the required quiescent current and noise performance levels.
