For the situation described in p342 above a modified design, Ask an Expert

Engineering

For the situation described in P3.42 above, a modified design is required for the situation in which the supply variation is ±5%, the Zener-diode nominal voltage variation is ±3%, and the load variation is from 2 to 10 mA. Find the value of R for which the minimum Zener current is 2 21n. For this situa-tion, what are the limits on the output voltage produced? Assume rz = 20 rz and Iza = 0.2 mA for all available zeners.
