Layout Consideration

For best performance of the LP3382S, the following

guidelines must be strictly followed.

※

Input and Output capacitors should be placed

close to the IC and connected to ground plane to

reduce noise coupling.

※

The GND and Exposed Pad should be connected

to a strong ground plane for heat sinking and

noise protection.

※

Keep the main current traces as possible as short

and wide.

※

LX node of DC-DC converter is with high

frequency voltage swing. It should be kept at a

small area.

※

Place the feedback components as close as

possible to the IC and keep away from the noisy

devices.
