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.

Abstract: A power supply circuit includes a first transistor and a second transistor electrically coupled between a power supply terminal and an output terminal. When a first current path, in which output terminal through the first transistor, is formed, a voltage level of the output terminal may be controlled to be greater than or equal to a predetermined level. When a second current path, in which a current flows from the power supply terminal to the output terminal through the second transistor, is formed, the voltage level of the output terminal may be controlled to be less than or equal to the predetermined level.
