CM431L
LOW VOLTAGE ADJUSTABLE SHUNT REGULATOR
GENERAL DESCRIPTION
FEATURES
The CM431L is a low voltage three terminal adjustable shunt regulator with thermal stability guaranteed over temperature. The output voltage can be adjusted to any value from 1.24V （VREF）to 18V with two external resistors. The CM431L has a typical dynamic output impedance of 0.25Ω. Active output circuitry provides a very sharp turn on characteristic, making the CM431L an excellent replacement for zener diodes.
LOW voltage operation（1.24V） Adjustable output voltage V0 = VREF to 18V Wide operating current range 60μA to 120mA LOW dynamic output impedance 0.25Ω typ. Trimmed bandgap design ± 0.5%
APPLICATIONS
The CM431L shunt regulator is available in four voltage tolerances（0.5%, 0.7%, 1.0% and 2.
