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.
