Abstract
A power source circuit includes a power source terminal for inputting a power source voltage; a switching regulator including a switching circuit connected to the power source terminal and a smoothing circuit connected to the switching circuit; a series regulator connected to the switching regulator in series; a switching portion; and a control portion. The smoothing circuit includes a capacitor and an inductor to output a first voltage. The series regulator is connected to the switching circuit and the smoothing circuit in series to output a second voltage. The switching portion supplies the power source voltage to the series regulator. The control portion outputs a switching signal for controlling the switching portion to turn on or off according to the power source voltage.
