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.
