The SO PowerPAD DAP is a thermal connection only that is
physically attached to the backside of the die, and used as a
thermal heat-sink connection.
Ground
The unregulated voltage input
No internal connection
The regulated output voltage
Soft-start capacitor connection. Used to control the rise time of V_OUT
at turnon.
