The voltage-reference circuit of Fig. P1.74 uses a Norton equivalent as a more realistic model for the load. Let the diode have rz 5 12 V and VZ 5 12 V at IZ 5 25 mA. (a) Assuming VI 5 (24 6 6) V, 2 kV # RL # 5 kV, and 0 # IL # 8 mA, specify a 5% standard resistance R for a guaranteed diode current of 4 mA. (b) What is the line regulation (in mV/V) and the load regulation (in mV/mA) of your circuit? (c) Estimate VO(max) and VO(min).
