Abstract:
A voltage regulator circuit with over-current protection, which includes a linear regulator, a voltage controller, and an over-current protection circuit. The linear regulator includes a converter and a driver. The converter is connected to a voltage input terminal and a voltage output terminal. An output terminal of the driver is connected to the converter for controlling the operation of the converter. The voltage controller is connected to the voltage output terminal, the output terminal and a first input terminal of the driver, respectively, for providing a feedback voltage. The over-current protection circuit is connected to the output terminal of the driver and the linear regulator. The over-current protection circuit detects the output voltage of the driver for comparing with a comparison voltage. When the output voltage is larger than the comparison voltage, the over-current protection circuit controls the driver to turn off the converter.
