D 3.52 Design a 7.5-V zener regulator circuit using a 7.5- V zener specified at 12 mA. The zener has an incremental resistance r, = 30 2 and a knee current of 0.5 mA. The regu- lator operates from a 10-V supply and has a 1.2-k2 load. What is the value of R you have chosen? What is the regula- tor 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 oper- ates at a current no lower than the knee current while the supply is 10% low?
