REF-431

Introduce
REF-431 is a high precision voltage reference source which used TL-431 from Texas Instruments. The TL431 is
three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial,
and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and
36V. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements
for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power
supplies.
