PRODUCTION DATA.
When powering the Vcc and Vcco pins from separate supply rails, TI recommends that the supplies to reach their regulation point at approximately the same time while ramping up, or reach ground potential at the same time while ramping down. Using simultaneous or ratiometric power supply sequencing prevents internal current flow from Vcc to Vcco pins that could occur when Vcc is powered before Vcco.
