Procurement Notes

Verify the specific suffix TBGT3 against the manufacturer's latest datasheet to confirm packaging and tape-and-reel specifications. Confirm RoHS compliance status directly with onsemi documentation as regulatory requirements may vary by region and production date. Ensure the sourcing channel provides authentic components to avoid counterfeit risks associated with obsolete or high-demand precision references.

Selection Notes

Select this component when a precise 2.048V reference is required with minimal quiescent current draw. Compare the ±0.2% initial accuracy and 15ppm/°C temperature coefficient against alternative references to ensure compatibility with system error budgets. Verify that the SOT-23-3 package footprint aligns with the PCB layout constraints and thermal management requirements of the target design.
