DESCRIPTION

The TL431 is an adjustable shunt regulator designed to act as

an open-loop error amplifier with a 2.5V temperature

compensated reference. Its highly accurate 1% bandgap

reference is perfect for applications requiring stability and

accuracy over temperature and life.

Sharp turn-on characteristics and a low temperature coefficient

make the TL431 an excellent replacement for many zener

diode applications, programmable to any value greater than

2.5V and up to 36V by using two external resistors. As a

combination error amplifier and reference, it can be used to

manage control loops such as switching power supplies.
