Voltage Reference Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance and packaging type matches project requirements. Review official documentation for handling precautions and storage conditions specific to this legacy part number.

Voltage Reference Selection Notes

Evaluate thermal stability and load regulation requirements against the 50 ppm/°C specification. Ensure circuit design accommodates the 15 mA maximum shunt current capability. Consider alternative packages if footprint constraints differ from the standard SOT-23 form factor.

Voltage Reference Part Context

This device belongs to the LM4050 series of precision micropower shunt voltage references. It shares architectural similarities with other members like the LM4050AIM3-25 but differs in accuracy grade and specific output voltage configuration within the same family lineage.

Voltage Reference Replacement Considerations

Official documentation indicates LM4050BEM3-2.5/NOPB as an alternate designation. Verify pinout compatibility and electrical specifications before substitution.
