Challenge Problems
Push your limits with advanced challenges
Design a Zener regulator for a circuit with V_in = 10V, V_Z = 5.1V, I_ZK = 2mA, and a load current I_L(max) = 8mA. Calculate R_S and ensure the power rating of the Zener is within limits.
💡 Hint: Ensure to monitor both the calculations for R_S and the maximum power rating.
Analyze the effects of varying V_in from 9V to 12V on the output voltage of your design and evaluate its line regulation.
💡 Hint: What happens to the current through R_S when input voltage changes?
