Start-up time is defined as the time from EN1 = EN2 = EN3 from 0 V to V
AVIN
to VOUT1, VOUT2, and VOUT3 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.
