Pin Description
Soft-Start capacitor connection. Used to slow the rise time of V_OUT at turn-on.
The unregulated voltage input pin.
Ground
The regulated output voltage pin.
The supply for the internal control and reference circuitry.
The TAB is a thermal connection that is physically attached to the backside of
the die, and used as a thermal heat-sink connection. See the Application
Information section for details.
