3-) The zener regulator shown in Figure 3 uses a current-amplifying device (CA) with the following
characteristics:
V2 = 0.6 V, 1, =100/,
where I, is the input current at terminal 1, 1, is the output current at terminal 2 and V, is the voltage between
terminals 1 and 2. The Zener diode has the i-v characteristic shown. The maximum Zener current is
1max = 50 mA (if the Zener current exceeds this maximum it is damaged).
(a) Find the output voltage V, for (i) V, = 10 V, and (ii) V, = 12 v.
(b) Find the maximum value of V, at which the Zener diode is not damaged.
