2-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 TPL51206 series devices are 2-A sink and source DDR termination regulators specifically designed for the DDR applications with heavy space limitation. The TPL51206 series devices implement a fast load-transient response and only requires a minimum output capacitance of 10μF.

The TPL51206 series devices support a remote-sensing function and all power requirements for DDR VTT bus termination. In addition, the TPL51206 series devices provide S3 and S5 control pins can be used to control the power state in DDR applications, setting OUT to high-impedance in S3 state (suspend to RAM) and discharging OUT and REFOUT in S4 or S5 state (suspend to disk).

The TPL51206 series devices are available in the thermally efficient 10-pin 2×2 DFN package with thermal pad, and support the operating temperature range from –40°C to +125°C.
