1. A voltage generation circuit comprising:
a plurality of voltage generation units generating different output voltages based on an input voltage,
wherein each of the plurality of voltage generation units comprises;
a plurality of resistors that are connected in series to detect the output voltages,
a comparison unit comparing a specific reference voltage with a divided voltage, wherein the divided voltage is a voltage which is obtained according to a voltage division between the at least one of the plurality of resistors and the others of the plurality of resistors, and
an output driver, connected between an input terminal applying the input voltage and an output terminal outputting the output voltages, controlled by the comparison unit,
wherein the comparison unit is coupled to and shared by the voltage generation units, and
wherein at least one of the plurality of resistors is coupled to and shared by the plurality of voltage generation units.
