Abstract
Aspects of the present invention include a low-dropout (LDO) linear power supply system. The system includes a pass-element configured to generate an output voltage at an output based on an input voltage. The system also includes a compensation amplifier stage coupled to the output and configured to provide frequency compensation and provide a desired frequency response of the output voltage. The system further includes a gain amplifier stage interconnecting the compensation amplifier stage and the pass-element and configured to provide DC gain scaling to generate the output voltage substantially proportional to the input voltage within a given range of the input voltage.
