Abstract:
1. A power source control circuit module comprising: a laminated body including a plurality of dielectric layers laminated on each other; a plurality of regulator devices mounted on a surface of the laminated body and including a switching regulator device; a first internal ground electrode connected to the plurality of regulator devices and arranged along substantially a whole surface of one of the plurality of dielectric layers within the laminated body; a first external ground connection terminal connected to the first internal ground electrode and provided on a back surface of the laminated body; a circuit element mounted on the back surface of the laminated body; a second internal ground electrode arranged along substantially a whole surface of one of the plurality of dielectric layers that is different from the first internal ground electrode; and a second external ground connection terminal connected to the second internal ground electrode and provided on the back surface of the laminated body; wherein the first internal ground electrode is electrically divided with respect to each of the plurality of regulator devices; individual electrodes of the divided first internal ground electrode are connected to the respective first external ground connection terminals; and the circuit element is connected to the second internal ground electrode.
