Feedback — Internally connected to the regulation, over-voltage, and short-circuit comparators. The regulation
reference point is 0.8V at this input pin. Connected the feedback resistor divider between the output and ground to set
the output voltage.
Exposed Pad — Internally connected to pin 4. Used to dissipate heat from the package during operation. Must be
electrically connected to pin 4 external to the package.
