ABSTRACT:
This semiconductor device has power source terminals for receiving a power source voltage and a voltage converting circuit for generating an output voltage lower than the power source voltage on a semiconductor chip. In particular, the voltage converting circuit has a constant voltage circuit for generating a reference voltage lower than the power source voltage, a voltage drop circuit which is connected to the power source terminal, and a differential amplifying circuit for controlling the conductivity of the voltage drop circuit in accordance with a difference between the output voltage of the voltage drop circuit and the reference voltage from the constant voltage circuit. This differential amplifying circuit generates a control voltage which linearly varies at a gentle slope in response to a change in feedback voltage near the reference voltage.
