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

due to excessive trace inductance.
