Abstract
A voltage regulator with an on/off control on the control terminal of the power transistor of the voltage regulator. The power transistor of the voltage regulator drives the conversion from a first voltage to a second voltage. The voltage regulator provides a power-saving switch at the control terminal of the power transistor, and includes a power-saving control circuit controlling the power-saving switch. When the power-saving switch is turned on, the control signal for the power transistor is conveyed into the control terminal of the power transistor. When the power-saving switch is turned off, the connection between the control signal for the power transistor and the control terminal of the power transistor broken.
