  • Circuit driving method and device
    Patent number: 9395729
    Abstract: A low dropout regulator includes a pre-regulation circuit, a sustaining circuit coupled to the pre-regulation circuit, and a pass element coupled to the sustaining circuit. The pre-regulation circuit is configured to generate a bias voltage. The sustaining circuit is configured to receive the bias voltage and an enable signal, and generate a control signal. The sustaining circuit is turned on or off by the enable signal. The pass element is configured to receive the control signal. When the enable signal turns on the sustaining circuit, the sustaining circuit generates the control signal according to the bias voltage so that a voltage value of the control signal is higher than a voltage threshold of the pass element. When the enable signal turns off the sustaining circuit, the sustaining circuit maintains the voltage value of the control signal above the voltage threshold of the pass element.
