SLUS984A –NOVEMBER 2009–REVISED APRIL 2012

SINK/SOURCE DDR TERMINATION REGULATOR

Check for Samples: TPS51200-Q1

FEATURES

APPLICATIONS

•

Qualified for Automotive Applications

•

Memory Termination Regulator for DDR,

DDR2, DDR3, and Low Power DDR3/DDR4

Input Voltage: Supports 2.5-V Rail and 3.3-V

Rail

•

Notebook/Desktop/Server

•

VLDOIN Voltage Range: 1.1 V to 3.5 V

Telecom/Datacom, GSM Base Station, LCD-

TV/PDP-TV, Copier/Printer, Set-Top Box

Sink/Source Termination Regulator Includes

Droop Compensation

DESCRIPTION

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.

•

Requires Minimum Output Capacitance of 20-

μF (typically 3 × 10-μF MLCCs) for Memory

Termination Applications (DDR)

•

PGOOD to Monitor Output Regulation

EN Input

The TPS51200 maintains a fast transient response

and only requires a minimum output capacitance of

20 μF. The TPS51200 supports a remote sensing

function and all power requirements for DDR, DDR2,

DDR3, and Low Power DDR3/DDR4 VTT bus

termination.

REFIN Input Allows for Flexible Input Tracking

Either Directly or Through Resistor Divider

•

Remote Sensing (VOSNS)

±10-mA Buffered Reference (REFOUT)

Built-in Soft Start, UVLO and OCL

Thermal Shutdown

In addition, the TPS51200 provides an open-drain

PGOOD signal to monitor the output regulation and

an EN signal that can be used to discharge VTT

during S3 (suspend to RAM) for DDR applications.

Meets DDR, DDR2 JEDEC Specifications;

Supports DDR3 and Low-Power DDR3/DDR4

VTT Applications

The TPS51200 is available in the thermally-efficient

SON-10 PowerPAD package, and is rated both

Green and Pb-free. It is specified from -40°C to

125°C.
