The Regulator ICs require minimum 1.5 higher input voltage than their voltage rating. For example 7805 IC requires minimum 6.5 volts to give 5 volt output. Here are some circuit designs of IC 7805 to ...

7805 IC requires minimum 6.5 volts to give 5 volt output. To monitor this, a Zener and LED are included at the input. Zener voltage is 4.7 volts and the forward voltage drop of the ordinary diffuse ...

We’re quite sure that all hobbyists have used the 7805 voltage regulator at least once in their lives. They are a simple way to regulate 7V+ voltages to the 5V that some of our low power ...
