PROBLEM TO BE SOLVED: To provide a semiconductor device capable of outputting a predetermined current by reducing variations of output currents of secondary side transistors, in a semiconductor device equipped with a current mirror circuit to which a plurality of the secondary side transistors are connected. SOLUTION: The secondary side transistors are disposed between a primary side transistor constituting the current mirror circuit and another primary side transistor, and a plurality of resistances are each connected in series between drains of the primary side transistors. Each gate of the secondary side transistors is connected between the resistances, respectively. Output currents of the secondary side transistors to which the gate voltages generated by the resistances are applied ensure a predetermined value. COPYRIGHT: (C)2007,JPO&INPIT
