Explanation: The equation for load current, IL = [(ß+1)IO]-[ß×(VEB(ON)/R1)]=[(15+1)×2]–[15×(1v/12 Ω)] =32-1.25 =30.75A. 5. Which type of regulator is considered more efficient?
A. All of the mentioned
B. Special regulator
C. Fixed output regulator
D. Switching regulator
Answer:A
Explanation: The equation for load current, IL = [(ß+1)IO]-[ß×(VEB(ON)/R1)]=[(15+1)×2]–[15×(1v/12 Ω)] =32-1.25 =30.75A. 5. Which type of regulator is considered more efficient?
A. All of the mentioned B. Special regulator C. Fixed output regulator D. Switching regulator
Explanation: The switching element dissipates negligible power in either on or off state. Therefore, the switching regulator is more efficient than the linear regulators. 6. State the reason for thermal shutdown of IC regulator?
