Voltage Reference Procurement Notes

Verify the specific suffix 'B' indicates the 0.2% accuracy grade and 'X' denotes tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation, as historical batches may vary. Check for end-of-life notifications or discontinuance alerts from Texas Instruments prior to procurement planning. Ensure the ordering part number matches the required accuracy and package type specifications exactly.

Voltage Reference Selection Notes

Select this component when a 2.5 V reference with 0.2% initial accuracy is required in a SOT-23-3 package. Compare against the LM4050CEM3X-2.5 if higher accuracy (0.5%) is acceptable but lower cost is prioritized, or against LM4050AIM3X-2.5 for tighter tolerance (0.1%). Consider the operating temperature range limits (-40°C to +85°C) against application requirements. Verify that the shunt current capability of 15 mA meets the circuit design needs.

Voltage Reference Part Context
