You are asked to design a Zener diode voltage regulator, as shown in Figure 1.e, to have a stabilized voltage of 3.3 V across the load R,. The Zener diode has a constant voltage of 3.3 V when its current is more than a minimum current of I0 mA and has negligible dynamic resistance. The load current changes between 0 mA (open circuit) and 200 mA. The input voltage Vi is equal to 5 V. i) Choose the value of series resistance Rs to have stabilized voltage at the output at all conditions. ii) Calculate the maximum current in the diode and the resistor Rs. Based on these values, choose the maximum power ratings of the diode and the resistor Rs
