Application: Low-dropout regulator and operation method thereof (Patent ID: US20230409065A1)

The patent filed by Realtek Semiconductor Corp. describes a low-dropout regulator that includes an amplifier circuit, buffer circuit, control circuit, power transistor, and feedback circuit. The amplifier circuit generates a first voltage based on input and reference voltages, while the buffer circuit generates a second voltage. The control circuit forms a noise canceller with the buffer circuit, and the power transistor generates an output voltage based on the input and second voltages. The feedback circuit generates a feedback voltage based on the output voltage.

The claims detail the components and configurations of the low-dropout regulator, including the use of transistors, resistors, capacitors, and bias voltages in the buffer and control circuits. The noise canceller is described as being formed by specific components within the regulator. The operation method involves generating voltages based on input and reference voltages, controlling the buffer circuit or noise canceller, and generating an output voltage. The method also includes specific steps for controlling the super source follower or source follower configurations within the regulator. Overall, the patent outlines a detailed design and operation method for a low-dropout regulator with noise cancellation capabilities.
