Description
The Bay Linear B431 is a three terminal adjustable shunt
regulator with thermal stability over Temperature range. Using
two external resistors allows the output voltage to be adjusted
from 2.5V to 36V. With a sharp turn on characteristics the
B431 a superior replacement for zener diode applications.
The B431 shunt regulator has a tolerance of 0.5% which has
proven to be sufficient to overcome all of the other errors in
the system to virtually eliminate the need for trimming in the
power supply manufacturers assembly line and contribute a
significant cost savings.
