Emitter Follower Application Circuit A simple voltage regulator circuit can be constructed using an emitter follower and a zener diode, as shown in figure 4. For this specific application, we would like to power a 12 Volt DC water pump from a solar panel. This type of application is quite common when the location of the water source is significantly far from power lines. The voltage from the solar panel varies...
