Voltage Reference Procurement Notes

Verify the exact suffix configuration against official Texas Instruments documentation to ensure correct voltage and accuracy specifications. Confirm RoHS compliance status and manufacturing origin through authorized channels. Check for recent Product Change Notifications or discontinuance notices that may affect long-term availability. Ensure sourcing from authorized distributors to guarantee authenticity and traceability.

Voltage Reference Selection Notes

Select this part when a 2.0 V reference with ±0.1% accuracy is required. Compare noise specifications and quiescent current against alternative references if low power is critical. Verify thermal management requirements given the small SOT-23-3 package size. Consider board layout constraints for shunt reference operation and ensure adequate current limiting resistors are included in the design.

Voltage Reference Part Context

This component is part of the LM4050 family of micropower shunt voltage references. The LM4050 series offers various fixed output voltages and accuracy grades. The 'A' grade indicates tighter initial accuracy compared to standard grades. The 'M3' suffix denotes the SOT-23-3 package type. The 'NOPB' indicates lead-free and RoHS-compliant construction.

Voltage Reference Replacement Considerations

Direct substitutes include other LM4050 variants with different voltage outputs or accuracy grades, such as LM4050AIM3X-2.5/NOPB or LM4050CEM3X-2.0/NOPB. Cross-reference with LM4040 series components if lower accuracy is acceptable. Verify pinout compatibility and electrical parameters before substitution.
