Abstract
A voltage regulator is provided that includes an error amplifier circuit having a reference voltage input port that receives a reference voltage, N input ports, N output ports, and N power transistors, where N is a positive integer that is greater than or equal to 2. Each of the power transistors has a gate that is connected to one of the N output ports. The error amplifier amplifies a difference between the reference voltage and each of N respective feedback voltages input to the N input ports, respectively, and outputs amplified voltages to the respective N output ports.
