Pin Description

PIN

DESCRIPTION

V

IN

This is the input supply voltage to the regulator. For LLP devices, both V

together for full current operation (500mA maximum per pin).

GND

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.

SNS

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

V

EN

The enable pin allows the part to be turned ON and OFF by pulling this pin high or low.

V

OUT

Regulated output voltage.
