If a large current is applied, the output voltage will drop.
When the current is small, there is no problem with output voltage = input voltage.
When the current flows up to the limit value max, the output voltage != Input voltage.
What is the cause of the difference between the output voltage and the input voltage?
Specifically, the input is 5.0V and the output is 3.7V.
When further current is applied, EN = Low and the output voltage becomes 0V.
