Abstract:
A power supply device comprising:an output terminal;output means for supplying an output current to a load connected to the output terminal;output voltage detection means for detecting an output voltage at the output terminal;output control means for controlling the output means in accordance with a result of detection by the output voltage detection means so as to keep the output voltage at a predetermined value;first means for outputting a monitoring current that varies in an identical manner with the output current;second means for feeding, when a value of the monitoring current output from the first means is higher than a predetermined value, an output current control signal to the output control means in order to instruct the output control means to reduce a value of the output current in such a way that, the higher the value of the monitoring current, the lower the value of the output current; anda capacitive element connected between an input terminal of the second means and the output terminal.
