Q5.

Find the answer (in mA) to Question 5 in the attached image where:

Vi(min) = 14 Volts, Vi(max) = 21 Volts,

IL(max) = 298 mA and VBE(sat) = 0.6 Volts.

 

Provide your answer rounded to 2 decimal places.

Question 5 Again consider the voltage regulator circuit shown in Figure 2. We would like to maintain the output voltage (v。) at a constant 5 V and allow a maximum load current (IL,max) through the load resistor (RL). Assume that the unregulated input voltage (vi (t)) varies from Vi,min volts to Vi,max volts. Assume that Ris set at 1kN and that the transistor operates in the active region. 1. Calculate the maximum zener current (iz). R vi (t)-WW iz V z iB il ic vi (t) to RL Figure 2: Circuit for Question 4 and Question 5.
