ABSTRACT:
Various apparatuses, methods and systems for a voltage regulator are disclosed herein. For example, some embodiments provide an apparatus for regulating a voltage including an N-channel transistor that is connected between an input and an output, an error amplifier that is connected to the output, a capacitor that is connected between the error amplifier and a gate of the N-channel transistor, and a comparator that is connected to a node between the error amplifier and the capacitor. The apparatus also includes a charge pump that is switchably connected to the gate of the N-channel transistor. The apparatus is adapted to connect the charge pump to the gate of the N-channel transistor when a voltage at the node between the error amplifier and the capacitor rises above a threshold voltage.
