CL431
DESCRIPTION
The CL431 is an adjustable shunt regulator designed to act as
an open-loop error amplifier with a 2.5V temperature
compensated reference. Its highly accurate 0.5% 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 CL431 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 CL431 can be used as a direct replacement for the
standard TL431.
