Abstract
A voltage regulator, including an amplifier, a voltage setting circuit and a power transistor, is provided. The amplifier includes a first current source and a second current source. The amplifier has two input terminals to respectively receive a reference voltage and a feedback voltage. The first current source is coupled between the operating power source and an output terminal of the amplifier, and provides a first current to the output terminal. The second current source is coupled between the output terminal and a reference ground terminal, and draws a second current from the output terminal. The voltage setting circuit is coupled to the output terminal, and increases a driving voltage on the output terminal according to the first current in a voltage bypass mode. The power transistor receives the driving voltage and generates an output voltage according to the driving voltage based on the operating power source.
