Abstract: A voltage regulator is connected with an input/output circuit. The voltage regulator includes a controlling circuit, a sink voltage generator and a source voltage generator. The controlling circuit generates a first reference voltage, a second reference voltage, a first power start control signal and a second power start control signal. The sink voltage generator receives the first reference voltage and the first power start control signal. The source voltage generator receives the second reference voltage and the second power start control signal. When the voltage regulator is in a normal working state, the controlling circuit inactivates the first power start control signal and the second power start control signal, the sink voltage generator generates a sink voltage according to the first reference voltage, and the source voltage generator generates a source voltage according to the second reference voltage.
