= 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.
