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. ORDERING INFORMATION TA PLASTIC MSOP POWER PAD (DGQ)(1) −40 °C to 85°C TPS51100DGQ (1) The DGQ package is also available taped and reeled. Add an R suffix to the device type (i.e., TPS51100DGQR). See the application section of the data sheet for PowerPAD drawing and layout information. PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
