  • Voltage regulating device and process
    Patent number: 6538417
    Abstract: A voltage regulating device includes a comparison circuit for comparing a voltage proportional to an output voltage to a fixed reference voltage. The fixed reference voltage is received on a first input and the voltage proportional to an output voltage is received on a second input. The voltage regulating device further includes a variable resistance-forming circuit controlled by the output of the comparison circuit and disposed so that the output voltage remains substantially constant. The voltage regulating device may be supplied with a variable input voltage. The voltage regulating device further includes a second comparison circuit so that the output voltage remains substantially constant if the input voltage is greater than a threshold, and substantially equal to the input voltage if the input voltage is less than the threshold.
