Driving this pin high enables the regulator, while pulling it low puts the regulator into shutdown mode GND 3 2 Ground OUT 4 1 Power Output Pin In PCB layout, prefer to use large copper area to cover this pad for better thermal dissipation, Exposed Pad — EP then connect this area to GND or leave it open. However, do not use it as GND electrode function alone
