Texas Instruments' model TPS51100DGQR voltage regulator chip is a 3-A, sink/source tracking terminal regulator. The device is specifically designed for low cost and low external component count systems where space is a premium.
The TPS51100DGQR maintains fast transient response and requires only a 20μF (2×10μF) ceramic output capacitor. According to JEDEC specifications, the TPS51100 supports telemetry and all features required to power DDR and DDR2 VTT bus terminations. The part also supports DDR3 VTT termination at 1.5V VDDQ (typical). In addition, the TPS51100 includes integrated sleep state control, placing VTT Hi-Z (suspend to RAM) in S3, and soft-off (suspend to disk) of VTT and VTTREF in S5. The TPS51100 is available in a thermally efficient 10-pin MSOP PowerPAD™ package with a temperature range of -40°C to 85°C.
