With the development of main processors in PCs and servers, more source double-data-rate (DDR) memories are required in the mainboard, where the input voltage becomes lower, and the space limitation becomes higher. The TPL51200 is a series of the 3-A sink and source DDR termination regulators, specifically designed for DDR applications with heavy space limitations. The TPL51200 series implements a fast load-transient response and only requires a minimum output capacitance of 20 μF. The TPL51200 series supports a remote-sensing function and meets all power requirements for DDR VTT bus termination. In addition, the TPL51200 series provides an open-drain PG signal for VTT regulation indication, and an EN signal that can be used to discharge VTT for DDR applications. The TPL51200 series is available in the thermally efficient DFN3×3-10 package with a thermal pad. The operating temperature range is from –40°C to +125°C.
