Layout Consideration
The output capacitors must be located as close to the
Vout terminal of the device as possible. It is recom-
mended to use a section of a layer of the PC board as a
plane to connect the Vout pin to the output capacitors to
prevent any high frequency oscillation that may result
from excessive trace inductance.
