POWER DISSIPATION AND LAYOUT INDICATIONS
The power is mainly dissipated by the two device buffers. It can be calculated by the equation:
P = (V
IN1
-V
OUT1
) x I
OUT1
+ (V
IN2
-V
OUT2
) x I
OUT2
The following table lists the different R

values of these packages with or without a heat sink and
the corresponding maximum power dissipation assuming:
G
Maximum Ambient Temperature = 70° C

for heat sinking
Copper area (cm2) (35 μm plus solder) Board is face-down
To optimize the thermal conductivity of the copper
layer and the exchanges with the air, the solder
must cover the maximum amount of this area.
