Procurement Notes

Verify the specific suffix TBGT3 against the manufacturer's official datasheet to confirm the exact output voltage and tolerance grade. Ensure the sourcing channel provides genuine onsemi components with traceable documentation. Check for RoHS compliance status as per current manufacturing standards. Confirm availability through authorized distributors to avoid counterfeit risks.

Selection Notes

Select this component when a fixed 3.3V reference with ±5% accuracy is required. Consider the 800nA supply current for low-power applications. Evaluate the 50ppm/°C temperature coefficient against environmental conditions. Compare the SOT-23-3 footprint with existing board layouts. Verify input voltage compatibility within the 2.7V to 5.5V range.

Part Context

This part belongs to the CAT8900 series of precision voltage references from onsemi. The series offers various fixed output voltages and accuracy grades.
