Voltage Reference Procurement Notes

Verify the specific suffix M3X corresponds to the SOT-23 tape and reel packaging configuration. Confirm that the ordering information aligns with the required initial accuracy tolerance level associated with this part number variant. Ensure compliance with RoHS standards as indicated in the datasheet specifications.

Voltage Reference Selection Notes

Select this component when a precision adjustable reference is required in a compact surface-mount footprint. Consider the thermal resistance characteristics of the SOT-23 package for power dissipation calculations. Evaluate the minimum cathode current requirements against the expected load conditions to ensure proper regulation across the operating temperature range.

Voltage Reference Part Context

This device belongs to the LM431SA/SB/SC family of programmable shunt regulators. It serves as a direct replacement for Zener diodes in many applications due to its sharp turn-on characteristic and lower dynamic impedance. The family offers various accuracy grades and package options to suit different design constraints.
