Function
Channel 1 output voltage pin
Channel 2 output voltage pin
Ground
Chanel 2 enable pin. This pin should be driven either high or low and must not
be floating. Driving this pin high enables channel 2 output, while pulling it low
puts Chanel 2 regulator into shutdown mode.
Power input pin
Chanel 1 enable pin. This pin should be driven either high or low and must not
be floating. Driving this pin high enables channel 1 output, while pulling it low
puts Chanel 1 regulator into shutdown mode.
In PCB layout, prefer to use large copper area to cover this pad for better
thermal dissipation, then connect this area to GND or leave it open. However
do not use it as GND electrode function alone.
