PNP Constant Current Source (CB1242E)

    The load current can be adjusted up to about 1 A. The transistor can be TIP32 or TIP42. The potentiometer P1 is wire and the transistor must be equipped with a heat radiator. Zener diodes close to the indicated values can be used. The circuit is from Robotics, Mechatronics and Artificial Intelligence by Newton C. Braga, published in the United States.
