Abstract
A semiconductor integrated circuit device has an output circuit composed of a P-channel transistor whose source is connected to a terminal for receiving a supplied voltage and an N-channel transistor whose source is connected to a terminal for receiving a ground voltage, with the node between the drains of the two transistors used as the output terminal of the output circuit. A capacitive circuit element is connected between the sources of the two transistors, and thus in parallel with the output circuit, so as to suppress variations that occur in the current supplied from the supplied power as a result of a current being fed through the output circuit to or from a load connected to the output terminal. This helps keep constant the voltage that is supplied to an internal circuit that is connected in parallel with the output circuit, and thereby stabilize the operation of the internal circuit.
