AS1431DR4DBVB General 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.
