Abstract
A power supply circuit that outputs via an output terminal an output voltage based on an input voltage applied to an input terminal includes: an inserted transistor of an N-channel depletion type inserted between the input terminal and an internal supply power terminal; and a regulator configured to generate the output voltage by using as a supply voltage a voltage applied to the internal supply power terminal. The gate of the inserted transistor is connected to the output terminal.
