Design a 7.5V zener regulator circuit using a 7.5V zener specifiedat 10mA. The zener has an incremental resistancerz=30Ω and a knee current of 0.5mA. Theregulator operates from a 10V supply and has a 1.2kΩ load. What is the value of R you have chosen? What isthe regulator output voltage when the supply is 10% high? Is 10% low? What is the output voltage when both the supply is10% high and the load is removed? What is the smallest possible load resistor that can be used while the zener operates ata current no lower than the knee current while the supply is 10%low?
