Description

The B431L is a three terminal adjustable shunt regulator with thermal stability of 50ppm/°C. The output voltage can be adjusted to any value from 1.24V (VREF) to 16V with two external resistors. These devices have a typical output impedance of 0.05. Active output circuitry provides a very sharp turn-on characteristics and making the device excellent replacement for zener diodes in many applications. The B431L is an ideal voltage reference in an isolated feedback circuit for 3.0V switch mode power supplies.

The B431L 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.
