Abstract
A capless regulator circuit is provided. The regulator circuit includes a power transistor that controls the supply of current to an external output terminal connected to a load; a monitor transistor provided between the external output terminal and a reference voltage terminal to which a reference voltage is supplied, and through which a current corresponding to the voltage of the external output terminal flows; a first constant current source that is provided in series with the monitor transistor and generates a first voltage according to the difference between the first current and a first constant current; and a cascode circuit that generates a second voltage that amplifies the first voltage and supplies it to the gate of the power transistor.
