Adjustable Shunt Regulator

Features

B3431

Description

•

Wide Operating Range …1mA to100mA

Tight Band Gap Tolerance ….….…0.5%

Low Temp. Coefficient…...…...30 ppm/^oC

Wide temp range of –40 to +105^oC

Available in SOT-23 package

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.
