traces, and GND should be connected to a ground
plane. To maximize package thermal dissipation
and power handling capacity of the AAT4285
SC70JW-8 package, the ground plane area con-
nected to the ground pins should be made as large
as possible. For best performance, C
should be placed close to the package pins.
