A 12 V power supply has ROUT of 20 m▲ at a maximum current of 1.5 A. The load regulation is
A)0.25%
B)0.75%
C)0.5%
D)none of the above

Question

Quizplus · Accepted Answer

The load regulation is defined as the change in output voltage divided by the change in load current, multiplied by 100%. In this case, the change in output voltage is 12 V - 11.9 V = 0.1 V, and the change in load current is 1.5 A - 0 A = 1.5 A. Therefore, the load regulation is 0.1 V / 1.5 A * 100% = 0.25%.
