The appendix is my schematic diagram, Vs:5V, found the following questions:
First, the output voltage of all channels of TLV3544 is 4.5V,
When I adjusted the output voltage of channel 1 to 0V,
I found that the other three output channels fell from 4.5V to 4.4V.
What is the reason for this drop problem? How to solve this problem?
