Abstract
A power supply circuit according to the present invention includes, for example, an output circuit arranged to generate a stabilized voltage from an input voltage using an output transistor, a filter circuit arranged to smooth the stabilized voltage using a resistor and a capacitor so as to generate an output voltage, and a charging circuit arranged to supply charging current to the capacitor without the charging current being passed through the resistor.
