PIN CONFIGURATION (Top View)

The CL1431 is an adjustable shunt regulator designed to act

as an open-loop error amplifier with a 2.5V temperature

compensated reference. Its highly accurate 0.4% 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 CL1431 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.

The CL1431 can be used as a direct replacement for the

standard TL431.
