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.
