Voltage Reference Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the exact part number with the latest datasheet to validate pinout compatibility and thermal characteristics before integration.

Voltage Reference Selection Notes

Select this component when a low-cost, adjustable shunt regulator is needed for low-voltage applications. It is suitable where space is limited due to its small SOT-23 footprint. Consider the 1% initial accuracy and 138 ppm/°C temperature coefficient for circuit stability requirements. Ensure the operating current remains within the specified 15 mA maximum limit.

Voltage Reference Part Context

This device belongs to the LMV431A family of low-voltage adjustable shunt regulators. It shares functional similarities with the standard LM431 but is optimized for lower voltage operations. The 'NOPB' designation indicates lead-free packaging compliant with environmental standards. It is designed to replace older discrete zener diode references in modern electronic designs.

Voltage Reference Replacement Considerations

Direct substitutes include LMV431BCM5/NOPB and LMV431ACM5X/NOPB. Verify package dimensions and electrical parameters match the original design requirements before substitution.
