This is the input supply voltage to the regulator. For LLP devices, both V
for full current operation (500mA 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
The enable pin allows the part to be turned ON and OFF by pulling this pin high or low.
Regulated output voltage.
