Note 1:
Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2:

= 5V and I
OUT
= 2.5A. These specifications are applicable for
power dissipations up to 50W.
Note 3:
See thermal regulation specifications for changes in output voltage
due to heating effects. Load and line regulation are measured at a constant
junction temperature by low duty cycle pulse testing.
