Pfoblgm: A 5.2-v Zener in Fig. 1 is specified to have V71= 5'2 v 0t l4=1p4, r' =1"00f,1' lzr=0.1m4 Vzr= Vzo. The maximum power dissipation of the diode Po =40mW. and a. b. Fig-L- Find Vzo. Find the maximum safe allowed current lz that the diode can deliver, if the diode has 10% tolerance on its voltage Vz. the minimum R, can be used while keeping 12 less than 507o of the diode maximum current. Starting from here consider Rs= SkO. d. Now a load Ru=SkO is connected across the diode. Find Vout, lz, ofld lu' e. When Rr is disconnected, find the line regulation (uor/y') defined as the change in Ve6 due to change in the power supply V* and deduce in Veul resulting from -lV change in V* f. the load regulation (vou/4) defined as in Vqu1 due in load lr and deduce in V66 resulting from lmA change in /1. \f =20 V
