Note 1: All devices are 100% production tested at T
J
= +25°C and +125°C. Limits at -40°C are guaranteed by design.
Note 2: Dropout voltage is defined as (V
IN
- V
OUT
) when V
OUT
is 98% of V
OUT
for V
IN
= 8V.
Note 3: Dropout voltage is defined as (V
IN
- V
OUT
) when V
OUT
is 98% of V
OUT
for V
IN
= 6V.
Note 4: Operation beyond the absolute maximum power dissipation is not guaranteed and may damage the part.
Note 5: Test at V
IN
= 8V (L/M), V
IN
= 6V (T/S), V
IN
= 5V (Z/Y/W/V).
