PCB Layout Considerations
While layout for linear devices is generally not as critical
as for a switching application, careful attention to detail
will ensure reliable operation.
•
•
Attach the part to a large copper footprint,
particularly the thermal pad on the underside
of the device, to enable better heat transfer,
particularly
internal power and ground planes.
Place the input, output, and bypass capacitors
close to the device for optimal transient
response and device behavior.

•
•
Connect all ground connections directly to the
ground plane whenever possible to minimize
ground potential diff erences on the PCB.
Ensure that the feedback resistors are placed as
close as possible to the feedback pins.
