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 D55 to 125C and is now available in the SOT-23 (5L)
package.
