The TPS53317RGBR accepts a 1V to 6V input rail and delivers a regulated 0.6V to 2V output — this covers VTT termination for DDR3 (1.5V), DDR3L (1.35V), and DDR4 (1.2V) without needing a separate bias supply.
ROHS3 compliant, with no lead or restricted-substance exemptions to track.
No — the TPS51100DGQ is a different DDR termination regulator in a 10-MSOP package with a 4.75V fixed input, while the TPS53317RGBR takes a 1V-6V input range and comes in a 20-VQFN. They are not pin-compatible and serve different board footprints.
Yes — the 0.6V to 2V output range includes the 1.2V VTT rail required by DDR4 memory systems.
