GT431VA
The GT431VA and GT432VA device are three-terminaadjustable shunt regulators, with a guaranteed thermalstability over applicable temperature ranges. The outputvoltage can be set to any value between VREF(approximately 1.25V)and 18v with two externalresistors. These devices provide a very sharp turn-oncharacteristic,makingthesedevicesexcellentreplacement for Zener diodes in many applicationsBoth the GT431A and GT432A devices are specifiedwith an initial tolerance of 0.5% at 25°C
