Using LTSpice, model the Zener diode circuit below. Use the provided diode model in bzx55c5v1.txt. Note: Some links to assist with using a subckt model in LTSpice have been provided on Blackboard. i) Plot $V_O$ versus $V_S$ for $V_S=0\dots 10\mathrm{V}$ ii) At what value of $V_S$ does the circuit start behaving like a regulator? iii) Estimate the Line Regulation $?V_O/?V_S$ from the plot of $V_O$ versus $V_S$. iv) Plot $V_O$ versus $I_L$, and use this to estimate the Load Regulation $?V_O/?{\mathrm{I}}_L$.
