ユレータ。[Claims for Utility Model Registration] An error amplifier that compares a voltage corresponding to an output voltage applied to a load with a reference voltage, and the output voltage of the error amplifier becomes a constant voltage corresponding to the reference voltage. MOSFET to control
and an overcurrent detection resistor connected between the MOSFET and the load, in which a capacitor is connected between the common connection point of the MOSFET and the overcurrent detection resistor and the input terminal of the error amplifier. A series regulator using a MOSFET, characterized in that AC feedback is applied to high frequency components to bypass an overcurrent detection resistor.
