Abstract: A regulating device for receiving a variable voltage and delivering a constant voltage includes a regulating element that includes a circuit for comparing the variable voltage with a reference voltage, a circuit for dividing the variable voltage by a factor, and a switching circuit for supplying the regulating element with a voltage equal either to the variable voltage or to the divided variable voltage. The switching circuit may be controlled by the comparison circuit in such a way that the regulating element is supplied with the variable voltage if a voltage condition is not satisfied and with the divided variable voltage if the voltage condition is satisfied.

Abstract: An integrated circuit electrically is supplied with a voltage and includes an output MOS transistor having a gate driven by an output of a logic circuit and a circuit for biasing the gate of the output MOS transistor. The circuit for biasing the gate is provided for lowering a gate-source bias voltage of the output MOS transistor in a conductive state in relation to the gate-source bias voltage that would otherwise be provided by the output of the logic circuit. The present invention is particularly applicable to output stages for I2C buses.

Abstract: A voltage regulator with a current limiter includes a voltage regulating circuit including an amplifier circuit and a feedback circuit. The amplifier circuit includes a ballast or pass resistor and the feedback circuit supplies a first feedback voltage to the amplifier circuit, which is compared to a reference voltage. The voltage regulator further includes a current limiter circuit including a current limiter transistor in series with the ballast transistor and an output of the voltage regulator and a feedback circuit supplying a second feedback voltage to a controller for controlling the current limiter transistor. The controller causes the current limiter transistor to operate between saturation and blocking conditions depending on whether the second feedback voltage, which is representative of the output of the voltage regulator, is above or below a predetermined threshold voltage.
