BCT431

Precision Adjustable Shunt Reference

General Description

The BCT431 is a three-terminal adjustable shunt regulator providing a highly accurate bandgap reference. The adjustable shunt regulator is ideal for a wide variety of liner applications that can be implemented using external components to obtain adjustable currents and voltages.

In the standard shunt configuration, the combination of low temperature coefficient (TC), sharp turn-on characteristics, low output impedance and programmable output voltage make this precision reference a perfect zener diode replacement.

The BCT431 precision adjustable shunt reference is offered in four bandgap tolerances: ±0.25%, ±0.5%, ±1.0%, and ±2.0%.
