The following is a series regulator power supply 6V to 9V. Preventing that have something through the circuit in. The parts that perform to heal strong a picture uses the integrated circuit op-amp 741 multi-purpose numbers in the character Comparator mode. The circuit protects the output transistors compose TR1-TR3. By the transistor TR1 perform straddle the acknowledge voltage resistors R3. Which have current work when about 250mA or more than flow through R3 when TR1 work truck loads C3 as a result will do way R5 10K package Resister values and thereafter 2 second railings. The voltage its will encourage enough. TR2 Cooperate TR1 which assemble Tiristor be rapidities are many onely. This circuit consumes current in the condition calmly do not arrive at Current 5mA and will fully protect a part 12mA railing to have sizes only.
