*Required if regulator is located more than 4" from power supply filter
capacitor.
Although no output capacitor is needed for stability, it does improve
transient response.
C2 should be used whenever long wires are used to connect to the load,
or when transient response is critical.
Note: Pin 3 electrically connected to case.
