Chapter 4, Problem 4.63(choose chapter or problem)
Design a 7.5-V zener regulator circuit using a 7.5-V zener specified at 10 mA. The zener has an incremental resistance rz = 30 and a knee current of 0.5 mA. The regulator operates from a 10-V supply and has a 1.5-k load. What is the value of R you have chosen? What is the regulator output voltage when the supply is 10% high? Is 10% low? What is the output voltage when both the supply is 10% high and the load is removed? What is the smallest possible load resistor that can be used while the zener operates at a current no lower than the knee current while the supply is 10% low? What is the load voltage in this case? D
