... DESCRIPTION The IP431A circuit is a monolithic three terminal programmable shunt regulator diode. The voltage reference operates as a low temperature coefficient zener which is programmable between V using two external resistors. The device has a wide operating current range 100mA and a typical dynamic impedance of 0.2 . Active output circuitry ...
