摘要： A low drop-out voltage regulator, an integrated circuit, a sensor and a method of providing a regulated voltage are provided. The low drop-out voltage regulator comprises a regulated voltage driver for providing the regulated voltage in response to a control voltage, a feedback-loop circuit for generating the control signal such that the regulated voltage driving circuit provides the regulated voltage, and a pull-up circuit for pulling up the regulated voltage to a supply voltage when a difference between the supply voltage and the control voltage is smaller than a predetermined threshold value. In the feedback-loop circuit a first feedback voltage or a second feedback voltage is generated, respectively, on basis of a first ratio and a second ratio between the feedback voltage and the regulated voltage. The second feedback voltage is generated instead of the first feedback voltage when the regulated voltage is pulled-up to the supply voltage.

摘要： A voltage switching circuitry comprises a switching arrangement with a given number N of switches in series between a first terminal receiving a first voltage and a second terminal receiving a second voltage. The first voltage level is higher than the second voltage level, and N is at least equal to 2. A voltage-by-N divider, having N−1 output taps, is arranged to divide the first voltage by N to a scaled down version of the first voltage having a voltage level below voltage max ratings of the switches. The N−1 output taps of the divider are arranged to respectively output N−1 third voltages having respective levels staged below the first voltage level. N−1 max voltage generators generate N−1 fourth voltages, respectively equal to the maximum of the second voltage and of each of the N−1 third voltages. A switch control unit generates N control signals using the N−1 fourth voltages. These N control signals have respective voltage levels staged between the first voltage level and the second voltage level. In addition, each of the N control signals controls one of the switches of the switching arrangement, respectively.
