Note 1: The maximum allowable power dissipation is a function of maximum operating junction temperature, T
J (max)
,
the junction to ambient thermal resistance, and
the ambient,
θ
JA
, and the ambient temperature T
A
. The maximum allowable power dissipation at any ambient temperature is given:
P
D (max)
= (T
J(max)
- T
A
)
θ
JA
.
Exceeding the maximum allowable power limit will result in excessive die temperature; thus, the regulator will go into thermal shutdown.
The
θ
JA
of the SPX8863 is 220
C/W mounted on a PC board.
Note 2: Not apply to 1.8V version.
