摘要： A voltage regulator includes a first transistor, a second transistor, a third transistor, a feedback unit, a comparison unit, a first control unit and a second control unit. The first transistor is controlled by the feedback unit and the comparison unit, for stabilizing the voltage of the output node. When the first control unit turns on the second transistor, the voltage of the output node rises. When the first control unit turns off the second transistor, it triggers the second control unit turning on the third transistor, so the first transistor is turned on completely. Therefore, when the third transistor is turned off, the first transistor can be controlled by the feedback unit and the comparison unit for stabilizing the voltage of the output node.

摘要： The present invention relates to a gate driving circuit, comprising a driver control circuit, a voltage following bias circuit, a pull up circuit and a MOS transistor. The driver control circuit receives an active signal and generates a pull up signal or a pull down signal. In case of the pull up signal, the MOS transistor is turned to the OFF state by the pull up circuit, and there is no current for the output load device. In case of the pull down signal, the MOS transistor is turned to the ON state by the voltage following bias circuit. The driving voltage for the gate of the MOS transistor has a constant voltage drop according to the external supply voltage. Therefore, the gate driving circuit of the present invention provides a constant current for the output load device.
