Product Summary
The TPS5110PW 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 TPS5110PW maintains fast transient response only requiring 20-μF (2 × 10μF) of ceramic output capacitance. The TPS5110PW 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 TPS5110PW 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 TPS5110PW is available in the thermally efficient 10-pin MSOP PowerPAD and is specified from -40 ℃ to 85 ℃. Applications include: DDR, DDR2 Memory Termination, SSTL-2, SSTL-18 and HSTL Termination.
