Notes:

(1) Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its

nominal value. This specification is not valid for output voltages below 2.2 V.

(2) Turn-on time is the time measured between the enable input just exceeding VEN high value and the output

voltage just reaching 95% of its nominal value.
