MP2007
3A, 1.3V–6.0V
DDR Memory Termination Regulator
The Future of Analog IC Technology
DESCRIPTION
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 a 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
o
C to 85
o
C.
