Description
This is the input supply voltage to the regulator. For LLP package 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.
Regulated output voltage.
The enable pin allows the part to be turned ON and OFF by pulling this pin high or low.
The adjust pin is used to set the regulated output voltage by connecting it to the external resistors
R1 and R2 (see Typical Application Circuit).
