2.5 Output Voltage Regulation
The output voltage load regulation with a 5-V input and a 25°C ambient
temperature is shown in Figure 26. The output voltage line regulation is
shown in Figure 27. Over the input voltage range of 4.0 V to 6.0 and the load
range of 0 A to 6 A, the output voltage varies less than 0.3%.
