Note 4:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings 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.
Note 5:
The maximum power dissipation is a function of T
,
θ
, and T
. The maximum allowable power dissipation at any ambient temperature
is P

. All numbers apply for packages soldered directly into a PC board.
Note 6:
For testing purposes, ESD was applied using human body model, 1.5k
in series with 100pF.
Note 7:
Typical Values represent the most likely parametric norm.
Note 8:
All limits are guaranteed by testing or statistical analysis.
Note 9:
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.
Note 10:
The minimum output current required to maintain regulation.
Note 11:

is 5A for LMS1585AEP and 3A for LMS1587EP.
Note 12:
