Abstract
A voltage regulator is provided. The voltage regulator provides an output voltage that is proportional to a digital multi-bit select signal. The voltage regulator includes a coarse voltage regulator and a fine voltage regulator. The coarse voltage regulator provides a coarse output voltage based on an output of a voltage divider selected based on the most significant bits of the select signal. The fine voltage regulator provides the output voltage from the coarse output voltage. The output of the fine voltage regulator is adjusted by adjusting the output of an adjustable current source that is provided to a resistor that is coupled between the output and one of the inputs of the fine voltage regulator.
