Note 1:
Parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation over the
specified temperature range.
Note 2:
The dropout voltage is measured from V
IN
to V
OUT
when V
OUT
is 2% below its nominal value. The nominal output voltage is
measured from V
OUT
to GND when V
IN
is 1V greater than V
OUT
. Defined only for V
OUT
≥
2.5V.
Note 3:
Soft-start time is defined as the time required for the output to rise from 10% of its nominal value to 90% of its nominal value.
Note 4:
For V
OUT
< 2V, V
IN
must be above 2.5V.
Note 5:
This is the maximum time OUT can be out of tolerance before a reset is issued. It is implemented to ensure that momentary
output glitches do not trigger a reset condition.
Note 6:
In startup mode, the blanking time counter is not started until the soft-start time has elapsed. The total time from startup to
FLAG
issued is t
SS
+ t
BLANK
.
