PCB Layout Considerations
Poor layout can degrade the performance of the regula-
tor and can be a contributory factor in EMI problems,
ground bounce, thermal issues, and resistive voltage
losses. Poor regulation and instability can result.
The following design rules are recommended:
. Place the bucket capacitors as close to the device as
possible and on the same side of the board. Use short
wide copper areas between the capacitor pins and
the device pins.
2. Place the input and output decoupling capacitors
as close as possible to the device and connect these
capacitors’ ground pads together to the ground plane
using multiple vias through a short wide copper
area.
3. Connect pin directly to the copper area under the
thermal pad.
4. The thermal pad at the center of the device is not
electrically connected. Connect this pad to the
ground plane using multiple vias.
5. Use a ground plane to further reduce noise
interference on sensitive circuit nodes.
