A semiconductor device which continuously outputs data in synchronism with a first clock includes a clock generator which generates a second clock from the first clock which is externally supplied, a flip-flop circuit which operates in synchronism with the second clock, and receives the data, an output buffer circuit which outputs the output data from the flip-flop circuit outside, and a power supply circuit which includes a bandgap reference circuit, generates a voltage controlled by the bandgap reference circuit, and supplies the voltage as a power supply voltage to the clock generator, the flip-flop circuit, and the output buffer circuit.
