1. For V
OUT(NOM)
< 2 V, V
IN
= 2.5 V.
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 output voltages below 2 V.
3. Guaranteed by design.
4. Turn-on time is time measured between the input just exceeding 90 % of its final value and the output voltage just reaching
95% of its nominal value.
