LM317 TIP36C 0-30V 0-5A Laboratory Power Supply

I have seen different versions of the power supply, even the same circuit has a halide designed as a battery charging circuit in the LM317 datasheet file and in some electronic books, but I did not have the opportunity to apply it. Nevertheless, the familiar power supply circuit such as the LM317, made with the materials used by many electronics, may attract more attention than others.A Laboratory type power supply circuit worth trying.

LM317 cannot power 5A normally, 2 TIP36C transistors are reinforced, LM301 opamp is used for current limiter and stabilizer control.

The LM301 R5 monitors the voltage drop on the 0.1 ohm shunt resistor and limits the current. However, the opamp needs negative voltage. The voltage is regulated by the LM7905 regulator taken from the additional winding of the transformer and applied to the opamp. Negative voltage can be generated with different circuits and can be used without additional winding or transformer (direct dc operation), but it is necessary to experiment, it is necessary to work .. Firstly, it is ideal to run the circuit and then switch to this type of experimental applications.
