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 regulator for digital loads combines a closed loop regulation circuit with an open loop topology. A transistor and a bank of transistors share the same voltage source VDD and gate control current. Each of the bank of transistors is sized to match different current load requirements and one or more may be switched in or out as appropriate when the digital load transitions from one operating mode to another. The regulator has good DC load regulation and unconditional stability regardless of output capacitance.

摘要： A low dropout voltage regulator is described having a pass device, differential amplifiers, and a feedback loop including a low pass filter. Two differential amplifiers arranged in parallel coupled to the low pass filter in the feedback loop provide a specified and stable DC voltage whose input-to-output voltage difference is low. Improved stability, reduced die area, improved power supply rejection ratio, increased bandwidth, decreased power consumption, and better electrostatic discharge (ESD) protection may result.
