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.
