OPERATIOU
thermally connected to the die substrate. Table 1 shows
measured thermal resistance from junction to ambient for
the LT1118 connected to various sized PC board ground
planes. The power dissipated in the LT1118 varies with
input voltage and loading. When the regulator is sourcing
current the power which must be dissipated by the pack-
age is:
P
D
= (V
IN
– V
OUT
) I
LOAD
.
When the regulator is sinking load current, power dissipa-
tion is nearly independent of V
IN
and can be calculated as:
P
D
= V
OUT
I
LOAD
.
Heat sinking to the IC package must consider the worst
case power dissipation which may occur.
