All electronic voltage regulators will have a stable voltage reference source which is provided by the reverse breakdown voltage operating diode called zener diode. Q1) design a voltage regulator using a zener diode that will maintain a constant output voltage around 5v, your design should meet the following specifications. The minimum zener current will occur when the load current is maximum.
