Voltage Reference Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status as documentation may vary by production batch. Check for discontinuation notices or lifecycle changes prior to finalizing procurement plans. Ensure the supplier provides valid traceability documents matching the manufacturer's part identification.

Voltage Reference Selection Notes

Select this component when a 2.5 V reference with 50 ppm/°C stability is required in a small footprint. Consider the 15 mA maximum shunt current limit for biasing requirements. Evaluate the 0.5% initial accuracy against system tolerance needs. Compare against the LM4040 series if lower cost or different temperature coefficients are acceptable for the application.

Voltage Reference Part Context

This part belongs to the LM4050 family of precision micropower shunt voltage references from Texas Instruments. It shares architectural similarities with other variants in the series but differs in output voltage and packaging options. The LM4050 series is designed to replace older discrete reference solutions while offering improved performance in a compact SOT-23 package suitable for modern surface-mount assembly processes.
