Voltage Reference Procurement Notes

Verify the complete part number including suffixes such as NOPB and packaging options like cut tape or reel when ordering. Confirm RoHS compliance status and ensure the supplier provides valid traceability documentation. Check for any recent product discontinuance notifications or process change notices that may affect availability or specifications before finalizing procurement decisions.

Voltage Reference Selection Notes

Select this component when a fixed 5 V reference with 0.1% accuracy is required in a small footprint. Consider the 50 ppm/°C temperature coefficient for thermal stability needs. Ensure the application current does not exceed the 15 mA maximum shunt limit. Evaluate the SOT-23-3 package constraints against board space requirements and thermal dissipation capabilities during system design.

Voltage Reference Part Context

This device is part of the LM4050 family of micropower shunt voltage references from Texas Instruments.
