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. The diagram below illustrates
proper layout of a circuit using the SC560A.
•
•
Attach the part to a large copper footprint, to
enable better heat transfer from the device
on PCBs where there are 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.
