Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status and ensure the supplier provides official datasheets matching the REF30xx family specifications. Cross-reference manufacturer part numbers to avoid confusion with similar variants.

Selection Notes

Select this component for designs requiring a compact, low-power voltage reference with tight initial accuracy. Ensure the input voltage remains within the specified 1.8 V to 5.5 V range. Consider the thermal management requirements given the operating temperature limits and package type.

Part Context

This part belongs to the REF30 series of voltage references from Texas Instruments. It shares architectural similarities with other members like the REF3012AIDBZR but differs in packaging format. The series is designed for general-purpose precision applications requiring small form factors.

Replacement Considerations

Direct substitutes include REF3012AIDBZR for reel-to-reel compatibility. Other compatible options within the same family may offer different output voltages or accuracies depending on specific design constraints.
