Abstract
A regulator circuit includes an output transistor that generates an output current in accordance with a control voltage that is applied to a control terminal of the output transistor. A differential amplifier provides feedback control of the control voltage in accordance with a level of the output current. A phase compensation circuit is connected to the differential amplifier and the control terminal of the output transistor. The phase compensation circuit adjusts an output impedance of the differential amplifier. The phase compensation circuit includes a variable resistor that decreases the output impedance of the differential amplifier when the output current increases.
