DESCRIPTION
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-
µF (2 × 10µF) 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. In addition,
the TPS51100 includes integrated sleep-state
controls placing VTT in High-Z in S3 (suspend to
RAM) and soft-off for VTT and VTTREF in S5
(suspend to disk). The TPS51100 is available in
the thermally efficient 10-pin MSOP PowerPAD
and is specified from −40
°C to 85°C.
