DESCRIPTION
This is the input supply voltage to the regulator. For LLP devices, both V
IN
pins must be tied
together for full current operation (250mA maximum per pin).
Circuit ground for the regulator. This is connected to the die through the lead frame, and also
functions as the heat sink when the large ground pad is soldered down to a copper plane.
Output sense pin allows remote sensing at the load which will eliminate 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 V
OUT
.
The enable pin allows the part to be turned ON and OFF by pulling this pin high or low.
