  • Linear voltage regulator utilizing a large range of bypass-capacitance
    Patent number: 9671805
    Abstract: Amplifiers, notably multi-stage amplifiers, such as linear regulators (e.g. low-dropout regulators) configured to provide a constant output voltage subject to load transients are presented. An amplifier is described, which comprises a first amplification stage configured to provide an intermediate voltage, based on an outer feedback voltage and based on a reference voltage. Furthermore, the amplifier comprises an output stage configured to provide a load current at an output voltage based on the intermediate voltage. In addition, the amplifier comprises an outer feedback circuit configured to derive the outer feedback voltage from the output voltage. The output stage comprises a buffer configured to provide a drive voltage based on the intermediate voltage and based on an inner feedback voltage derived from the output voltage. The buffer comprises a pass device which is configured to provide the load current at the output voltage based on the drive voltage.
