Abstract
A semiconductor device which controls output of a plurality of voltages is provided. A power supply control circuit which drives the semiconductor device includes a reference voltage generating circuit and a stabilized power supply circuit. The stabilized power supply circuit has a function of outputting a voltage input from a sample-and-hold circuit and amplified by the amplifier circuit. A control circuit has a function of setting an output voltage of the power supply control circuit. The sample-and-hold circuit in the stabilized power supply circuit includes a transistor whose on/off state is controlled. In such a configuration, a voltage set by the control circuit can be held and output.
