Description
LM431A and LM431B are three terminal adjustable precision shunt regulators With guaranteed thermal stability over a full operation temperature range..
The output Voltage of these ICs can be set to any value between VREF (Typical 2.50V) and the corresponding maximum cathode voltage (36V) with two external resistors..
These devices feature the sharp turn-on characteristics, low temperature coefficient and low output impedance, making them ideal substitute for Zener Dio.
