Voltage Reference Procurement Notes

Verify that the ordering suffix 'X' corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm that the 'NOPB' designation indicates lead-free material compliance and RoHS standards. Ensure the SOT-23-5 package dimensions align with the target PCB footprint design constraints before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a low-voltage adjustable shunt regulator with superior initial accuracy compared to standard variants is required. The 0.5% tolerance distinguishes it from lower-precision alternatives, making it suitable for sensitive measurement circuits. Consider the 15 mA current limit when designing load conditions to ensure stable regulation without exceeding maximum ratings.

Voltage Reference Part Context

This part belongs to the LMV431 family of low-voltage adjustable precision shunt regulators. It serves as a specialized variant offering tighter initial tolerance specifications than standard models. The family is designed to replace traditional Zener diodes in applications demanding higher stability and lower voltage operation capabilities.
