Description

The AS1431 is a three-terminal adjustable shunt regulator providing a

highly accurate 0.4% 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

coefficient (TC), sharp turn-on characteristics, low output impedance and

programmable output voltage make this precision reference a perfect

zener diode replacement.

The AS1431 is characterized to operate over the full automotive tem-

perature range of Ð55 to 125¡C and is now available in the SOT-23 (5L)

package.
