5 In the simple voltage regulator circuit shown in
Figure P9.53, R must maintain the Zener diode current
within its specified limits for all values of the source
voltage, load current, and Zener diode voltage.
Determine the minimum and maximum values of R
which can be used.
V, = 5 V+ 10%
iz min = 3.5 mA
Vs = 12 +3 V
1, = 15 2
izmax = 65 mA
IL = 70+ 20 mA
