Claim:
1. A voltage regulator, comprising: an error amplifier having a first input terminal for receiving a reference signal, a second input terminal for receiving a feedback signal, and an output terminal for generating an intermediate control signal; a first voltage buffer connected to the output terminal of the error amplifier for receiving the intermediate control signal and generating a control signal; a transistor having a gate terminal connected to the first voltage buffer for receiving the control signal, a first terminal for receiving a supply voltage signal, and a second terminal for generating a regulated output signal; a frequency compensation circuit connected to the second terminal of the transistor; a first capacitor having a first terminal connected to the output terminal of the error amplifier and a second terminal connected to the frequency compensation circuit; and a resistive network connected to the second terminal of the transistor for receiving the regulated output signal and outputting the feedback signal, wherein the frequency compensation circuit comprises:
