电压调节器具有输入端子和接地端子。所述电压调节器包括高侧器件、低侧器件、以及控制器。所述高侧器件耦合在所述输入端子与中间端子之间。所述高侧器件包括第晶体管和第二晶体管，所述第晶体管和所述第二晶体管各自耦合在所述输入端子与所述中间端子之间，以使得所述第晶体管控制所述第二晶体管的源漏开关电压。所述低侧器件耦合在所述中间端子与所述接地端子之间。所述控制器驱动所述高侧器件和所述低侧器件交替地将所述中间端子耦合到所述输入端子和所述接地端子。 A voltage regulator has an input terminal and a ground terminal. The voltage regulator includes a high-side device, a low side device, and a controller. The high-side device is coupled between the input terminal and an intermediate terminal. The high-side device includes first and second transistors each coupled between the input terminal and the intermediate terminal, such that the first transistor controls a drain-source switching voltage of the second transistor. The low-side device is coupled between the intermediate terminal and the ground terminal. The controller drives the high-side and low-side devices to alternately couple the intermediate terminal to the input terminal and the ground terminal.
