Abstract
A regulated power source circuit is provided with a current output circuit including a drive stage transistor which operates when receiving at the input side thereof an output signal from one of transistor for differential operation in a differential amplifier circuit, a current output stage transistor which is driven by the drive stage transistor and a detection circuit which detects a drive current value of the drive stage transistor, and further a dummy circuit which causes to output from the other transistor forming a pair with the one transistor in the differential amplifier circuit a current the value of which is substantially equal to that of the current outputted from the one transistor in the differential amplifier circuit to the drive stage transistor when a detection signal from the detection circuit is received.
