The purpose of the present invention is to provide a semiconductor integrated circuit apparatus that has a negative feedback amplification circuit or a voltage descending circuit for effectively responding to the fluctuations of power source voltage and realizing the stabilization of output voltage. A bias current with its consumption current set by a constant current source is flowing through the differential amplification MOSFET. A capacitor, which is used to detect the decrease of external power source voltage, is disposed between the external power source voltage and the specified circuit node. According to the external power source fluctuations and using the current flowing through a capacitor, the operation current of the differential amplification MOSFET is increased so as to make it possible to conduct a stabilizing operation onto the output voltage to handle the decrease of the external power source voltage.
