Abstract
In certain aspects, a voltage regulator includes a pass transistor coupled between an input of the voltage regulator and an output of the voltage regulator, and an amplifier having a first input coupled to a reference voltage, a second input coupled to the output of the voltage regulator via a feedback path, and an output. The voltage regulator also includes a voltage booster coupled between the output of the amplifier and a gate of the pass transistor. In certain aspects, the voltage booster includes a first capacitor and a second capacitor for double charge pumping. In certain aspects, a control circuit of the voltage booster is coupled to a voltage source that is independent of an output voltage of the amplifier.
