PinNameFunctionsNotes
ENEnable
GPIO
Allows the part to be turned ON and OFF by pulling this pin HIGH or LOW.
GNDGround
GND
Circuit ground for the regulator. For TO-252 and SOT-223 packages, it functions as a heat sink when soldered down to a large copper plane.
INInput Supply Voltage
POWER
The input supply voltage to the regulator. For WSON devices, both IN pins must be tied together for full current operation (500 mA maximum per pin).
OUTOutput Voltage
POWER
Regulated output voltage.
SNSSense Pin (WSON only)
GPIO
Allows remote sensing at the load which eliminates the error in output voltage due to voltage drops caused by the resistance in the traces between the regulator and the load. This pin must be tied to VOUT.
DAPExposed Pad (WSON only)
GND
Functions as a thermal connection when soldered to a copper plane.
