Abstract
A linear voltage regulator includes a transistor, an error amplifier, a feedback circuit and a compensation circuit. The transistor has a first terminal for receiving an input voltage, a second terminal for providing an output voltage, and a control terminal. The error amplifier has a first input terminal, a second input terminal and an output terminal, wherein the first input terminal receives a reference voltage, and the output terminal is coupled to the control terminal of the transistor. The feedback circuit receives the output voltage and generates a feedback voltage lower than the output voltage. The compensation circuit is configured to receive the feedback voltage and generate a compensation voltage at the second input terminal of the error amplifier. The compensation circuit includes a compensation capacitor for introducing a zero point into an open-loop transfer function of the linear voltage regulator to improve system stability.
