を特徴とする過負荷保護回路。An overcurrent of a constant voltage power supply having a current detection section that detects the output current as a proportional voltage, and a first comparator that controls the power control section and reduces the output voltage by the output when the detected voltage and the reference voltage match. In the load protection circuit, the load protection circuit includes a voltage storage section for storing a voltage corresponding to the constant voltage, a voltage storage section for detecting a difference between a voltage corresponding to the output voltage and a voltage in the storage section, and flowing a current from the storage section in the direction of decreasing the reference voltage. An overload protection circuit comprising two comparators.
