定化電源回路。The DC stabilization system has a stabilization control system that detects the output voltage of the output transistor that supplies current to the load and controls the base current of the output transistor based on the detected value, and stabilizes the voltage supplied to the load. In the power supply circuit, there is a control element connected to the output side of the output transistor to detect an overvoltage higher than a preset voltage, and a control element connected to the base side of the output transistor to detect an overvoltage that is higher than a preset voltage, and a control element connected to the base side of the output transistor to control the output transistor based on the output of the control element when an overvoltage is output. A DC stabilized power supply circuit characterized in that an overvoltage protection system having a switching element for cutoff is provided separately from the stabilization control system.
