High current in the range from 0 to 5 And can be obtained from the circuit shown in Fig. 1.41. The output voltage depends on the integrated circuit regulator. For voltage 6 is applied IC 7806 and 12 were used In IC 7812.
The transistor Q1 must be installed on the radiator. The resistor R1 connecting base to the emitter of the transistor determines the point of opening of the transistor. Note, this scheme is not protected against short circuits.
