The TL1431 is a precision programmable reference with specified thermal stability over automotive, commercial,
and military temperature ranges. The output voltage can be set to any value between VI(ref) (approximately 2.5 V)
and 36 V with two external resistors. This device has a typical output impedance of 0.2 Ω. Active output circuitry
provides a very sharp turnon characteristic, making the device an excellent replacement for Zener diodes and
other types of references in applications such as onboard regulation, adjustable power supplies, and switching
power supplies. …
