1. How is the Thevenin or output resistance of a power supply related to the load regulation? For a quality power supply, should the output resistance be high or low?
2. The manufacturer of a three-terminal regulator recommends using a bypass capacitor on the input if the IC is more than 6 in from the unregulated power supply. What is the purpose of this capacitor?
3. What is the typical dropout voltage for the LM78XX series? What does it mean?
