Inspire the Linear Power
Adjustable Shunt Regulator
B3431
Description
Features
The Bay Linear B3431 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 B3431 a superior replacement for
zener diode applications.
.
The B3431 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.
