Page No. : 1/1 Array RS431 Series
Adjustable Precision Shunt Regulator
Description
The RS431 series are three-terminal adjustable regulators with
guaranteed thermal stability over applicable temperature ranges. The
output voltage may be set to any value between V REF (approximately 2.5
volts) and 36 volts with two external resistors. These devices have a
typical dynamic output impedance of 0.2Ω. Active output circuitry provides
a very sharp turn-on characteristic, making these devices excellent
replacement for zener diodes in many applications.
