Procurement Notes

Verify the specific suffix TBGT3 against the manufacturer's official datasheet to confirm the exact output voltage, tolerance class, and packaging configuration. Ensure compatibility with your system's thermal management requirements given the SOT-23-3 package size. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed 2.048 V reference with ±0.06% accuracy is required. Consider its low 800 nA supply current for battery-operated designs. Evaluate the 50 µVp-p noise specification against your application's sensitivity needs. Compare the SOT-23-3 footprint constraints with available board space. Verify that the 10 mA output drive capability meets the load requirements of your downstream circuitry.

Part Context

This part belongs to the CAT8900 series of precision analog voltage references from onsemi. The series offers various fixed output voltages and tolerance grades to suit different precision applications. The B suffix typically denotes a specific accuracy bin within the product line. These devices are designed to replace older discrete reference solutions in modern compact electronic designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the CAT8900 family offering similar voltage and tolerance. Verify that any substitute maintains the same SOT-23-3 package and electrical characteristics. Consult onsemi documentation for approved cross-references or updated part numbers.
