Adjustable Precision Shunt Voltage
Regulator
LA431A LA431B
Adjustable Precision Shunt
Regulator
General Description
• LA431A and LA431B are three terminal Adjustable PrecisionShunt
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 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 Diode in many applications such as switching power supplly, charger and other adjustable
regulators.
• LA431 precis...
