RECOMMENDED OPERATING CONDITIONS
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
J
A
, 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
J
A
, exceeding the maximum allowable power limit will result in excessive die temperature; thus, the
regulator will go into thermal shutdown. The
θ
J
A
of the SPX5205 is 220
°
C/W mounted on a PC board.
Note 2:
Not applicable to output voltages of less than 2V.
