Abstract

A semiconductor integrated circuit includes a functional circuit and a power source voltage generating circuit used for operating the functional circuit. In the power source voltage generating circuit, output stage transistors are driven by comparing a plurality of reference voltages produced by a plurality of resistors connected in series to one another with output voltages of a plurality of differential amplifiers connected in parallel to one another and varying gate voltages.
