MP2007

3A, 1.3V–6.0V

DDR Memory Termination Regulator

The Future of Analog IC Technology

DESCRIPTION

FEATURES

•

VDDQ Voltage Range: 1.3V to 6.0 V

Up to 3A Integrated Sink/Source Linear

Regulator with Accurate VREF/2 Divider

Reference for DDR Termination

Requires Only 20uF Ceramic Output

Capacitance

Drive Voltage Range: 4.5 V to 5.5 V

1.3V Input (VDDQ) Helps Reduce Total

Power Dissipation

Integrated Divider Tracks VREF for VTT

and VTTREF

Kelvin Sensing (VTTSEN)

±20mV Accuracy for VTT and VTTREF

Built-In Soft-Start, UVLO and OCL

Thermal Shutdown

The MP2007 integrates the DDR memory

termination regulator with the output voltage

(VTT) and a buffered VTTREF outputs is a half

of VREF.

•

The VTT-LDO is a 3A sink/source tracking

termination regulator. It is specifically designed

for low-cost/low-external component count

systems, where space is a premium.

•

The MP2007 maintains

fast transient

•

response only requiring 20uF (2x10uF) of

ceramic output capacitance. The MP2007

supports Kelvin sensing functions.

•

The MP2007 is available in the 8-pin MSOP with

Exposed PAD package and is specified from

−40^oC to 85^oC.

APPLICATIONS

•

Notebook DDR2/3 Memory Supply and

Termination Voltage in ACPI Compliant

Active Termination Busses
