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.
NOTES 3:
The maximum power dissipation is a function of Tj
(MAX)
,
Θ

. The maximum allowable power
dissipation at any ambient temperature is P

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.
