Abstract
According to one embodiment, a constant voltage circuit includes: a first gain stage that outputting a first voltage amplifying a difference voltage between a divided voltage of an output voltage and a reference voltage; a second gain stage outputting a second voltage amplifying the first voltage; a second transistor, one end of which is coupled to the input voltage terminal, and other end of which is coupled to an output voltage terminal, controlling the output voltage to be constant in accordance with the second voltage applied to the gate; and a first circuit selecting one of a first operation mode and a second operation mode. When the first operation mode is selected, a first current flows to the first node, and when the second operation mode is selected, a second current flows to the first node.
