3-TERMINAL ADJUSTABLE VOLTAGE REGULATOR
HTL431
Description
The HTL431are three-terminal adjustable regulator series with a guaranteed thermal stability
over applicable temperature ranges The output voltage may be set to any value between VREF
(approximately 2.5 volts)and 36 volts with two external resistors These devices have a typical
dynamic output impedance of 0.2W Active output circuitry provides a very sharp turn-on
characteristic, making these devices excel lent replacement for zener diodes in many
applications.
