Overview
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 TPL51201 is a series of 3-A sink and source DDR termination regulators specifically designed for DDR applications with heavy space limitations. The TPL51201 series implements a fast load-transient response and only requires a minimum output capacitance of 20 μF.
The TPL51201 series supports a remote-sensing function and all power requirements for DDR VTT bus termination. In addition, the TPL51201 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 TPL51201 series is available in the thermally efficient DFN3x3-10 package with a thermal pad, and supports the operating temperature range from –40°C to +125°C.
