Abstract
The voltage regulator, entirely of monolithic integrated circuit construction, has an output voltage with a temperature gradient similar to that of the saturation and threshold voltages of liquid crystal elements. Constant current flows through temperature sensitive resistive elements in series with temperature insensitive resistance elements. The output voltage taken across at least a portion of the resistance elements has a voltage/temperature characteristic similar to that of the temperature sensitive elements. Both the level of the output voltage and the temperature gradient of the output voltage are independently controllable and independent of source voltage variations. Buffer circuits may be used between the output of the regulator and load, and sampling techniques are also used to conserve energy by duty cycle operation of higher current circuit elements.
