Disclosed is an apparatus for supplying voltages, wherein current supplying performance is improved without increasing the power supply capacity inside of an integrated circuit device. The apparatus is provided with the integrated circuit device, and a voltage supply section, which generates a drive voltage and supplies the drive voltage to the integrated circuit device. The integrated circuit device has: a plurality of circuits; a plurality of voltage input terminals, which receive, from the outside, a drive voltage for driving a corresponding circuit among the circuits; and a reference terminal, which outputs a reference voltage to be the reference of the drive voltage to be received from the outside. The voltage supply section generates the drive voltage, which is obtained by power-amplifying the reference voltage. |
