摘要：
In certain aspects, a voltage regulator includes a pass device coupled between an input of the voltage regulator and an output of the voltage regulator. The voltage regulator also includes an amplifying circuit having a first input, a second input, and an output, wherein the first input is configured to receive a reference voltage, the second input is coupled to the output of the voltage regulator via a feedback path, and the output of the amplifying circuit is coupled to a gate of the pass device. The voltage regulator further includes a first current source coupled between a supply rail and the amplifying circuit, and a capacitor coupled between the first current source and the output of the voltage regulator.
