The TPS51100 is a 3-A sink/source tracking
termination regulator. It is specifically designed for
low-cost/low-external component count systems,
where space is a premium.
The TPS51100 maintains fast transient response,
only requiring 20 μ F (2 × 10 μ F) of ceramic output
capacitance. The TPS51100 supports remote sensing
functions and all features required to power the DDR
and DDR2 VTT bus termination according to the
JEDEC specification. The part also supports DDR3
VTT termination with VDDQ at 1.5 V (typ). In addition,
