Description

The RS431 and RS432 device are three-terminal adjustable shunt regulators, with a guaranteed thermal stability over applicable temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5V) and 36V with two external resistors. These devices have provides a very sharp turn-on characteristic, making these devices excellent replacement for Zener diodes in many applications.

Both the RS431 and RS432 devices are offered in two grades, with initial tolerances (at 25°C) of 0.5% and 1%, for A and B grade.
