Description

The B432 is a three terminal adjustable shunt regulator with thermal stability of 50ppm/°C. The output voltage can be adjusted to any value from 1.25V (VREF) to 15V with two external resistors. The B432 is an ideal voltage reference in an isolated feedback circuit for 3.0V switch mode power supplies
 
The B432 shunt regulator is available with three voltage tolerances (0.5%, 1.0% and 2.0%) and three package options (SOT-23-3, TO-92, 8SOIC).  This allows the designer the opportunity to select the optimum combination of cost and performance for their application.
