A voltage regulator circuit uses a Zenerdiode that exhibits a total voltage of 5.2 V at 20 mA and has aresistance Rz = 20 W. The regulator operates froma 10 V supply and has a 1 kW load.
A) Use the node voltage method at the output node to derive anexpression for Vo in terms of Vs.
B) Find the value of R (use the regulator circuit diagram givenin class) to get an output voltage vo = 5 V.
C) Find the line regulation.
D) Find the load regulation.
E) Find the change in vo resulting from a ±1 V change in the supply voltage.
