Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
Production tested at T
A
= +25°C. Overtemperature limits are guaranteed by design.
Note 2:
Device tested at internally set voltage.
Note 3:
Dropout voltage for L/M versions is defined as (V
IN
- V
OUT
) when V
OUT
equals 98% of the nominal value of V
OUT
when
V
IN
= 11V. For T/S versions, dropout voltage is defined as (V
IN
- V
OUT
) when V
OUT
equals 98% of the nominal value of V
OUT
when V
IN
= 9.3V.
Note 4:
Observe the absolute maximum power dissipation limits.
