Start-up time is defined as the time from the moment EN1 = EN2 = EN3 transfers from 0 V to VAVIN to the moment VOUT1, VOUT2, and VOUT3 are reaching 90% of
their nominal levels. Start-up times are shorter for individual channels if another channel is already enabled. See the Typical Performance Characteristics section for
more information.
