2. Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its nominal value; this
specification does not apply for nominal output voltages below 1.6 V.
3. Turn-on time is the time measured between the enable input just exceeding V

high value and the output voltage just
reaching 95% of its nominal value.
