Challenge Problems
Push your limits with challenges.
Question 1
A voltage regulator presents a load regulation of 8% between its V_NL of 12V and a V_FL of 11V. Calculate the percentage increase in load current and comment if this is adequate for sensitive components.
💡 Hint: Understand how the output voltage relates to its stability for sensitive circuits.
Question 2
You have a Zener diode with a rated voltage of 5V and measures 5.5V under light loads. What improvements would you suggest for better load regulation, and how would you validate them?
💡 Hint: Consider how component adjustments affect the overall circuit performance.
