Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted, and distributors may not stock this item. Verify end-of-life status and lead times carefully before design finalization. Consider alternative sourcing channels or qualified replacement parts due to discontinuation risks.

Selection Notes

Select this part when a 3 V reference is required in a compact SOT-23 footprint. Ensure input voltage remains between 2.7 V and 5.5 V for proper regulation. Evaluate thermal management needs given the 50 PPM/C coefficient. Confirm that the 10 mA output capability meets downstream circuit requirements.

Part Context

Part of the CAT8900 family of precision voltage references designed for space-constrained applications. The D suffix indicates specific tolerance and performance grades within the series. This model complements other variants offering different fixed output voltages while maintaining consistent low-power characteristics and small form factor packaging.

Replacement Considerations

Verify cross-reference availability through authorized distributors. Check pinout compatibility and electrical parameter alignment with potential substitutes. Consult official obsolescence notices for recommended upgrade paths.
