Abstract
A voltage regulator and method applied thereto are provided. The voltage regulator generates a regulated voltage in response to a reference voltage and a control code. The voltage regulator includes a voltage divider circuit, an amplifier circuit, and a power MOS array. The voltage divider circuit is configured to divide the regulated voltage to generate a feedback voltage. The amplifier circuit is configured to amplify a voltage difference between the reference voltage and the feedback voltage to generate a bias voltage. The power MOS array includes multiple transistors. Each transistor has a first terminal coupled to a power rail, a second terminal coupled to the regulated voltage, and a control terminal selectively coupled to either the power rail or the bias voltage in response to the control code.
