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 2 Irs. For this situation, what are the limits on the output voltage produced? Assume rz = 20 0 and fa la 0.2 inA for all available senors.
