APPLICATION INFORMATION
Layout Consideration
AIC1383B is in SO-8 (DDR1/2), TO-252-5
(DDR1/2)
resulting in unable to dissipate heat easily when it
operates in high current. In order to prevent
maximum junction temperature exceeded, the
suitable copper area has to use.

The large copper at V
the heat dissipation is relieved. Using via to lead
heat into the bottom layer to strengthen as below
figures show.
All capacitors should be placed as close as
possible to relative pins.
VREF - Reference voltage input. Pull
VOUT - Output pin.
