ABSOLUTE MAXIMUM RATINGS
NOTES
Note 1:
The maximum allowable power dissipation is a function of maximum operating junction temperature, T
the junction to ambient thermal
resistance, and the ambient
θ
JA
, and the ambient temperature T
. The maximum allowable power dissipation at any ambient temperature is
given: P
= (T
-T
)/
θ
, exceeding the maximum allowable power limit will result in excessive die temperature; thus, the regulator will
go into thermal shutdown. The
θ
of the SPX3819 is 220
°
C/W mounted on a PC board.
Note 2:
Not applicable to output voltage 2V or less.
