B3431
Description
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.
