Product Summary

The TPS51200 is a sink/source Double Data Rate (DDR) termination regulator specifically designed for low input voltage, low-cost, low-noise systems where space is a key consideration. The TPS51200 maintains a fast transient response and only requires a minimum output capacitance of 20μF. The TPS51200 supports a remote sensing function and all power requirements for DDR, DDR2, DDR3, and Low Power DDR3/DDR4 VTT bus termination. The applications of the include Memory Termination Regulator for DDR, DDR2, DDR3, and Low Power DDR3/DDR4, Notebook/Desktop/Server, Telecom/Datacom, GSM Base Station, LCD-TV/PDP-TV, Copier/Printer, Set-Top Box.
