Objective is to design a current limiting circuit with a variation input voltage between 5 volts - 36 volts. The output current must not exceed 21 mA at 36 volts. Using a PZTA56 PNP transistor, LM234 Current Limiter IC, 1.2 Zener Diode. Cant seem to simulate it or replicate the outcome on a breadboard. Any help is appreciated!
