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. For the TO-252 and SOT-223 packages this is thermally connected
to the die and functions as a heat sink when the soldered down to a large 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.
LLP Only - The DAP (Exposed Pad) functions as a thermal connection when soldered to a copper
plane. See
