The Integrated Circuit TL431 is a regulator diode with 3 terminals adjustable shunt regulation with the specified thermal stability and and applicable in the automotive, commercial and optimum temperature range applications. The output of the IC can be easily programmed with resistor adjusting and changing the values. The monolithic integrated circuit voltage operates at a low temperature coefficient of Zener diode easily programmable with the adjustable resistors. The negative and positive voltages are defined with the help of this IC reference.
The device exhibit wide range of current 1.0 mA to 100 mA with the dynamic resistance and impendence offering. The stable reference voltage is also taken to operate for the shunt regulator and it can be used as a positive or negative voltage reference.
