Voltage Reference Procurement Notes

Verify the complete part number including suffixes such as NOPB and BEM3X, as these indicate specific accuracy grades and packaging types. 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 long-term availability or specifications.

Voltage Reference Selection Notes

Select this component when a 10V fixed reference is required in a small SOT-23-3 footprint. Ensure the application circuit can maintain the minimum operating current while staying within the 15 mA maximum shunt current limit. Consider the 50 ppm/°C temperature coefficient against the system's thermal environment requirements.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades in compact packages. The LM4050 series is designed for applications where low power consumption and high precision are critical, serving as a drop-in replacement for older generation references in many designs.

Voltage Reference Replacement Considerations

Direct substitutes include other LM4050 variants with different output voltages or accuracy grades, provided the pinout remains compatible. Cross-referencing with similar shunt references from other manufacturers requires verifying electrical parameter equivalence and thermal performance characteristics.
