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.

Abstract: A voltage regulator includes an operational amplifier, a transistor, a first resistor, a second resistor, an output voltage delaying circuit and a selecting circuit. The output voltage delaying circuit receives an output voltage and generates a delayed output voltage. A first input terminal of the selecting circuit receives a reference voltage. A second input terminal of the selecting circuit receives the delayed output voltage. An output terminal of the selecting circuit generates a control voltage to a first input terminal of the operational amplifier. If the reference voltage is larger than the delayed output voltage, the selecting circuit selects the delayed output voltage as the control voltage. If the reference voltage is smaller than the delayed output voltage, the selecting circuit selects the reference voltage as the control voltage.

Abstract: A power system includes a voltage regulating system and a digital circuit. The voltage regulating system receives a power down signal. The voltage regulating system selectively generates an output voltage according to the power down signal. When the digital circuit receives the output voltage, the digital circuit is operated. When the digital circuit is not operated, the power down signal is activated. After the external voltage source is switched on and before a voltage of the external voltage source reaches a fixed voltage, the voltage regulating system ignores the power down signal and generates the output voltage. After the voltage of the external voltage source reaches the fixed voltage, the voltage regulating system generates the output voltage if the power down signal is inactivated; the voltage regulating system stops generating the output voltage if the power down signal is activated.
