Bay Linear Inspire the Linear Power Adjustable Shunt Regulator 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. Features Wide Operating Range …1mA to100mA Tight Band Gap Tolerance ….….…0.5% Low Temp. Coefficient…...…...30 ppm/oC Wide temp range of –40 to +105oC Available in SOT-23 package . 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.
