Abstract
A current limiter includes: a P type MOS transistor electrically coupled between a main power potential supply line supplying power supply potential Vcc and a power potential supply line; and a level converter generating a control signal of signal levels in an operating state and a standby state, respectively, corresponding to a ground potential Vss and an intermediate potential Vhh (Vss<Vhh<Vcc) adjustable externally. The control signal is inputted into the gate of the transistor. The transistor supplies a sufficient operating current for ensuring an operating margin and a standby current of a prescribed value or less satisfying a requirement for lower power consumption onto the power potential supply line in the operating state and the standby state, respectively.
