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.
