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 15 - 14.7 = 0.3 V, and the change in load current is not given. However, we can assume that the load current is changing from minimum to maximum, which is the worst-case scenario. Therefore, the load regulation is 0.3 V / (maximum load current - minimum load current) * 100. Since the maximum and minimum load currents are not given, we cannot calculate the exact load regulation. However, we can say that the load regulation is less than 2%, because 0.3 V / (maximum load current - minimum load current) * 100 < 2%.
