Description
The TL432 series are three-terminal adjustable regulators with
guaranteed thermal stability over applicable temperature ranges. The
output voltage may be set to any value between VREF (1.24 or 1.25
volts) and 18 volts with two external resistors. These devices have a
typical dynamic output impedance of 0.2:. Active output circuitry provides
a very sharp turn-on characteristic, making these devices excellent
replacement for zener diodes in many applications.
