+ 0.5V, T
A
= -40°C to +85°C, unless otherwise noted. Typical values are at T
A
= +25°C.) (Note 1)
Note 1: Limits are 100% production tested at T
A
= +25°C. Limits over the operating temperature range are guaranteed through
correlation using Statistical Quality Control (SQC) Methods.
Note 2: The dropout voltage is defined as V
IN
- V
OUT
, when V
OUT
is 100mV below the value of V
OUT
for V
IN
= V
OUT
+ 0.5V.
Note 3: Time needed for V
OUT
to reach 95% of final value.
