The diode D1 is used as over-voltage protection on the evaluation
boards. It is not specifically required in the final circuit layout in
a system using a DC regulator.
Component R1 is shown in the silkscreen but is not used for this
configuration.
L3 - the 0 ohm resistor - can be removed (with a thru line) in the
final circuit layout.
