AS2431 Datasheet | ASTEC

Description The AS2431 is a three-terminal adjustable shunt regulator providing a highly accurate bandgap reference. The adjustable shunt regulator is ideal for a wide variety of linear applications that can be implemented using external ponents to obtain adjustable currents and voltages. In the standard shunt configuration, the bination of low temperature coefficient (TC), sharp turn-on characteristics, low output impedance and programmable output voltage make this precision reference an excellent error amplifier. The AS2431 is a direct replacement for the AS431 in low voltage, low current applications. It is also available in the very small footprint SOT23.
