Adjustable Precision Zener Shunt Regulator
General Description
The LM431 is a 3-terminal adjustable shunt regulator with
guaranteed temperature stability over the entire temperature
range of operation. The output voltage may be set at any level
greater than 2.5V (V
external resistors that act as a voltage divided network. Due
to the sharp turn-on characteristics this device is an excellent
replacement for many zener diode applications.
