Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free packaging compliant with RoHS standards. Confirm the '-ADJ' designation matches the required adjustable voltage functionality rather than fixed variants. Ensure the SOT-23-3 package footprint aligns with the target PCB design constraints before procurement.

Voltage Reference Selection Notes

Select this component when an adjustable reference is needed within the 1.24 V to 10 V range. The 0.1% accuracy and 50 ppm/°C stability make it suitable for precision applications. Consider the 12 mA maximum cathode current limit for load requirements. The SOT-23-3 package is ideal for space-constrained designs.

Voltage Reference Part Context

This part belongs to the LM4051 series of precision micropower shunt voltage references from Texas Instruments. It complements fixed-voltage options like the LM4051BIM3X-1.2/NOPB by providing user-defined output flexibility. The series is designed for applications requiring high accuracy in small form factors.

Voltage Reference FAQ
