A Zener diode is connected in a voltage regulator circuit as shown in Figure P2.21. The Zener voltage is VZ = 10 V and the Zener resistance is assumed to be rz = 0. (a) Determine the value of Ri such that the Zener diode remains in breakdown if the load current varies from IL = 50 to 500 mA and if the input voltage varies from VI = 15 to 20 V. Assume IZ (min) = 0.1IZ (max). (b) Determine the power rating required for the Zener diode and the load resistor.
