DESCRIPTION

The RS431 series are three

‐terminal adjustable

regulators with guaranteed thermal stability over

applicable temperature ranges. The output voltage

2.5V) and 36V 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.
