TPL51200 Series 3-A Sink and Source DDR Termination Regulator
■With the development of main processors in PCs and servers, more and more source double-data-rate (DDR) memories are required in the mainboard, where the input voltage becomes lower and lower, and space limitation becomes higher and higher.
■The TPL51200 series devices are 3-A sink and source DDR termination regulators specifically designed for the DDR applications with heavy space limitation. The TPL51200 series devices implement a fast load-transient response and only requires a minimum output capacitance of 20 μF.
■The TPL51200 series devices support a remote-sensing function and all power requirements for DDR VTT bus termination. In addition, the TPL51200 series devices provide 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 devices are available in the thermally efficient 10-pin 3×3 DFN package with thermal pad, and support the operating temperature range from –40℃ to +125°C.
