Abstract: A regulator having improved voltage control capability may include a comparator, an output voltage generator, a voltage divider, and an output voltage controller. The comparator generates a comparison voltage by comparing a reference voltage with a feedback voltage. The output voltage generator generates an output voltage by using a power supply voltage, based on the comparison voltage. The voltage divider may include a first resistor and a second resistor, which generate the feedback voltage by dividing the output voltage. The output voltage controller adjusts a resistance value of at least one of the first resistor and the second resistor, based on a result of comparing the output voltage with a target voltage.
