1.25V Adjustable Shunt Regulator

B432
























Pin Connection


Description

The B432 is a three terminal adjustable shunt regulator with
thermal stability of 50ppm/°C. The output voltage can be
adj ed to any value from 1.25V (V
REF
) to 15V with two
exte nal 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.
