1. Not applicable for VOUT(NOM) ≥ 5.0 V.

2. Turn-on time is time measured between the enable input just exceeding VEN high value and the output voltage just reaching

98% of its nominal value.

Note:

Values over the temperature range are guaranteed by design and correlation and not tested in production.
