The SC431 is a three terminal adjustable shunt

regulator with thermal stability guaranteed over

temperature. The output voltage can be adjusted to any

value from 2.5V (V

resistors. The SC431 has a typical dynamic output

impedance of 0.25 . Active output circuitry provides a

very sharp turn on characteristic, making the SC431 an

excellent replacement for zener diodes.

The SC431 shunt regulator is available with four

voltage tolerances (0.5%, 1.0% and 2.0% over T

to +85
