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 (V
REF
) 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.
