< 1.2 V, V
IN
= 1.5 V.
2. All transient values are guaranteed by design, not production tested.
3. 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 output voltages below 1.5 V.
4. Turn-on time is time measured between the enable input just exceeding V
EN
high value and the output voltage just
reaching 95 % of its nominal value.
