Programmable Precision Reference
Description
The TL431Z is a three-terminal adjustable
regulator series 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.The
TL431Z is characterized for operation from -
