Overview
The TPS51100DGQR, manufactured by Texas Instruments, is a 3-A sink/source tracking termination regulator designed for low-cost and low external component count systems where space is at a premium. This device is particularly suited for applications requiring fast transient response and minimal output capacitance, supporting only 20 µF (2 × 10 µF) of ceramic output capacitance. It is compliant with JEDEC specifications, offering features necessary for DDR and DDR2 VTT bus termination, and also supports DDR3 VTT termination at 1.5 V VDDQ. The TPS51100DGQR includes integrated sleep-state controls, placing VTT in Hi-Z during S3 (suspend to RAM) and softly shutting down VTT and VTTREF in S5 (suspend to disk). It is available in a thermally efficient 10-pin MSOP PowerPAD™ package, operating over a temperature range of -40°C to 85°C.
