DESCRIPTION
I
The Enable (EN) pin allows the part to be turned ON and OFF by pulling this
pin HIGH or LOW.
Circuit ground for the regulator. For the TO-252 and SOT-223 packages this
— is thermally connected to the die and functions as a heat sink when soldered
down to a large copper plane.
This is the input supply voltage to the regulator. For WSON devices, both IN
I pins must be tied together for full current operation (500 mA maximum per
pin).
O Regulated output voltage.
WSON only - Output sense pin allows remote sensing at the load which
I
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.
WSON only - The DAP (Exposed Pad) functions as a thermal connection
— when soldered to a copper plane. See WSON Mounting section in Layout for
more information.
