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