The TL431, A, B is a three-terminal adjustable regulator
with a guaranteed thermal stability over applicable temperature
ranges. The output voltage may be set to
any value between Vref (approximately 2.5 volts) and
40 volts with two external resistors. These devices have
a typical dynamic output impedance of 0.2Ω. Active
output circuitry provides a very sharp turn-on characteristic,
making these devices excellent replacement
for zener diodes in many applications.
