sipation of the LM3103 will produce excessive junction tem-
perature during normal operation, making good use of the PC
board’s ground plane can help considerably to dissipate heat.
The exposed pad on the bottom of the LM3103 IC package
can be soldered to the ground plane, which should extend out
from beneath the LM3103 to help dissipate heat. The exposed
pad is internally connected to the LM3103 IC substrate. Ad-
ditionally the use of thick traces, where possible, can help
conduct heat away from the LM3103. Using numerous vias to
connect the die attached pad to the ground plane is a good
practice. Judicious positioning of the PC board within the end
product, along with the use of any available air flow (forced or
natural convection) can help reduce the junction temperature.
