PROBLEM TO BE SOLVED: To provide a power source circuit capable of efficiently adjusting electric current flowing in each of error amplifiers with respect to a plurality of voltage regulators. SOLUTION: The electric current flowing in the error amplifiers AMP1 and AMP2 of two voltage regulators can be simultaneously adjusted by simultaneously adjusting the electric currents supplied by a NMOS transistors Me1 and Me2 as current sources by selectively cutting off a trimming element of a driving current setting circuit 3.
