Abstract
A semiconductor device including a power supply circuit to supply power to a circuit formed on a main substrate equipped with a circuit module is made smaller in size. A semiconductor device includes: a circuit module including a module substrate and a circuit element mounted on the module substrate; and a main substrate on which the circuit module is mounted. The semiconductor device further includes a power supply circuit to supply power to at least a circuit formed on the module substrate. The power supply circuit includes: a voltage generating circuit to output a predetermined output voltage; a first capacitor; and a second capacitor larger in capacity than the first capacitor. The voltage generating circuit and the first capacitor are mounted on the module substrate. The second capacitor is mounted on the main substrate.
