    The TPS54120 is an integrated switcher and low-dropout (LDO) regulator optimized for high efficiencies and a low-noise output. This application report describes how to use the Enable, Power Good, and Slow Start pins in tracking and sequencing applications. Three different tracking and sequencing methods are described in this report: sequential, ratiometric, and simultaneous. Each of these methods
