Description
The AS2431 is a three-terminal adjustable shunt regulator providing a highly accu-
rate bandgap reference. The adjustable shunt regulator is ideal for a wide variety
of linear applications that can be implemented using external components to
obtain adjustable currents and voltages.
In the standard shunt configuration, the combination of low temperature coeffi-
cient (TC), sharp turn-on characteristics, low output impedance and program-
mable output voltage make this precision reference an excellent error amplifier.
The AS2431 is a direct replacement for the AS431 in low voltage, low current appli-
cations. It is also available in the very small footprint SOT-23.
