Note 1:
Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the de-
vice outside of its rated operating conditions.
Note 2:
The maximum allowable power dissipation is a function of the maximum junction temperature, T
, the junction-to-ambient thermal resistance,
θ
, and the
ambient temperature, T
. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown.
The value of
θ
(for devices in still air with no heatsink) is 60C/W for the TO-220 package, 80C/W for the TO-263 package, and 174C/W for the SOT-223 package.
The effective value of
θ
JA
can be reduced by using a heatsink (see Application Hints for specific information on heatsinking).
Note 3:
ESD rating is based on the human body model: 100 pF discharged through 1.5 k
.
Note 4:
All limits guaranteed for T
= 25C are 100% tested and are used to calculate Outgoing Quality Levels. All limits at temperature extremes are guaranteed
via correlation using standard Statistical Quality Control (SQC) methods.
Note 5:
Dropout voltage is defined as the input-output differential voltage where the regulator output drops to a value that is 100 mV below the value that is measured
at V
IN
= 5V.
