Voltage Reference Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm RoHS compliance status and lead time requirements. Ensure the procurement channel provides valid traceability for the NOPB variant. Cross-reference the datasheet revision history to validate electrical characteristics before integration into production designs.

Voltage Reference Selection Notes

Select this component when precise shunt regulation is required in through-hole applications. The 0.5% initial accuracy suits tight tolerance designs. Consider the 97 PPM/C temperature coefficient for thermal performance needs. Verify that the TO-92 package fits the mechanical constraints of the target PCB layout.

Voltage Reference Part Context

This part belongs to the LM431 family of adjustable precision Zener diodes. It serves as a direct replacement for standard Zener references in many analog control loops. The NOPB suffix indicates a non-Pb (lead-free) manufacturing process compliant with global environmental standards.
