Abstract
A voltage regulator including an amplifier, a start signal generator and a power transistor is provided. The amplifier has a first positive input terminal, a second positive input terminal, and a negative input terminal to receive a start signal, a reference voltage and a feedback voltage respectively. An output terminal of the amplifier generates a driving voltage. The start signal generator is coupled to the first positive input terminal of the amplifier and generates the start signal, which is incremental, during a startup time interval in a voltage bypass mode. The power transistor generates an output voltage according to the driving voltage based on an operating power. In the voltage bypass mode, the reference voltage is equal to the operating power. A soft-start effect can be effectively achieved by the voltage regulator in the voltage bypass mode.
