IPC: G05F1/56
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To provide the protecting circuit which can protect a transistor(TR) controlling a load current in addition to the simultaneous improvement of the response speed and stability of a constant voltage circuit. SOLUTION: A load which is connected to an output terminal 109 is fed with electricity from a power feeding power source 104 through a resistor 105 for transmission admittance adjustment and a TR 103. The deviation of the output voltage at an output terminal 109 from the reference voltage of a reference power source 101 is detected by an operational amplifier 102. The output voltage of the operational amplifier corresponding to the deviation is applied to the TR 103 and converted into a current to control the load current. When the voltage drop across the resistor 111 which varies as the load current varies exceeds a specific value, a current control means 100 suppresses the feed current of the TR 103 and a by-pass capacitor 108 connected to the current output terminal of the TR 103 prescribes frequency characteristics of a feedback circuit.
