NOTES 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating
Rating indicate conditions for which the device is intended to be functional, but specific performance is not
guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
NOTES 2:
Power Dissipation is kept in a safe range by current limiting circuitry. Refer to Overload Recovery
in Application Notes.
NOTES 3:
The maximum power dissipation is a function of Tj
(MAX)
,
Θ
jA
and T
A
. The maximum allowable
power dissipation at any ambient temperature is P
D
=(Tj
(MAX)
– T
A
)Θ
jA
.
NOTES 4:
Typical Values represent the most likely parametric norm
NOTES 5:
All limits are guaranteed by testing or statistical analysis
NOTES 6:
I
FULL LOAD
is defind in the current limit curves . The I
FULL LOAD
curve defines the current limit as a function of
input-to-output voltage .
NOTES 7:
Load and Line regulation are measured at constant junction temperature , and are guaranteed up
to the maximum power dissipation of 30W.Power dissipation is determined by the input/output differential and
the output current. Guaranteed maximum power dissipation will not be available over the full input/output
range.
NOTES 8:
Dropout voltage is specified over the full output current range of the device.
