be floating. Driving this pin high enables channel 1 output, while pulling it low
E
puts Chanel 1 regulator into shutdown mode.
N
In PCB layout, prefer to use large copper area to cover this pad for better —

Thermal PAD

thermal dissipation, then connect this area to GND or leave it open. However do not use it as GND electrode function alone.
