| 发明名称 | Digital low drop-out regulator | ||
| 摘要 | A low drop-out regulator circuit includes a control circuit and a switching device. The control circuit has an output node. The switching device has a first terminal coupled with the output node of the control circuit. The switching device is configured to receive an input voltage at a second terminal of the switching device and provide an output voltage at a third terminal of the switching device. The control circuit is configured to provide a digital signal at the output node of the control circuit based on a feedback voltage of the output voltage at the third terminal of the switching device. | ||

| 主权项 | 1. A low drop-out regulator circuit comprising: a control circuit having an output node; and a switching device having a first terminal coupled with the output node of the control circuit, wherein the switching device is a transistor;the switching device is configured to receive an input voltage at a second terminal of the switching device and provide an output voltage at a third terminal of the switching device; andthe control circuit comprises: a first comparator configured to generate a first-comparator output signal based on comparing a first predetermined reference voltage and a feedback voltage, the feedback voltage being a scaled representative of the output voltage at the third terminal of the switching device; anda flip flop configured to generate a digital signal at the output node of the control circuit based on the first-comparator output signal. | ||
