PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device that can keep a low phase compensation capacitance even if an external load having a high load capacity is connected.SOLUTION: The semiconductor integrated circuit device has an output buffer having a first MOS transistor and a second MOS transistor connected in series between a supply voltage terminal and a ground voltage terminal, and outputting an output current from a first junction of the first and second MOS transistors. The semiconductor integrated circuit device further has a bias voltage generation circuit outputting a bias voltage based on a reference voltage to the first MOS transistor, and a bias adjustment circuit having a phase compensation capacitance and adjusting a gate voltage of the second MOS transistor on the basis of the reference voltage and a voltage of the first junction. |
