Pin Functions

DESCRIPTION
WSON Only - The DAP (exposed pad) functions as a thermal
— connection when soldered to a copper plane. See WSON Mounting
section for more information.
I
The EN pin allows the part to be turned to an ON or OFF state by
pulling this pin high or low.
Circuit ground for the regulator. For the SOT-223 package this is
— thermally connected to the die and functions as a heat sink when the
soldered down to a large copper plane.
This is the input supply voltage to the regulator. For WSON devices,
I both IN pins must be tied together for full current operation (250 mA
maximum per pin).
— No internal connection.
The ADJ pin is used to set the regulated output voltage by connecting
O it to the external resistors R1 and R2 (see Typical Application
Circuits).
I Regulated output voltage.
