摘要： A power control semiconductor device includes a voltage control transistor, a control circuit, a bias circuit, and external terminals. The voltage control transistor is connected between a voltage input terminal and an output terminal. The bias circuit generates a voltage that operates the control circuit. Output control signals provided from an outside are input to the external terminals to control an output voltage. The control circuit includes an error amplifier and a logic circuit. The error amplifier outputs a voltage corresponding to a potential difference between a reference voltage and a voltage divided by a voltage divider that divides the output voltage. The logic circuit generates: a signal that changes the divided voltage in accordance with the output control signals; and a signal that stops operation of the bias circuit in response to a combination of the output control signals.

摘要： A regulator includes a transistor connected between an input and an output. A feedback voltage controls the transistor to keep the output voltage constant. A first circuit functions as a comparator to compare a detection voltage from the output of the transistor and the feedback voltage when the output current is higher than a predetermined value, and functions as a buffer when the output current is lower than the predetermined value. A second circuit receives a reference voltage, the feedback voltage, and an output from the first circuit, and generates (i) a difference between the feedback voltage and the first circuit output when the reference voltage is lower than the first circuit output, and (ii) a difference voltage between the feedback voltage and the reference voltage when the reference voltage is higher than the first circuit output, and supplies a control voltage to control the output of the transistor.
