Abstract
A power supply circuit has a first node, a second node, a DC-DC converter that includes a switched capacitor, generates an output voltage based on an input voltage supplied from the first node, and outputs the output voltage from the second node, and a regulator that is connected in parallel to the DC-DC converter between the first node and the second node and controls an output current flowing to the second node based on a reference voltage lower than the input voltage.
