The Future of Analog IC Technology
MP20073
2A, 1.3V–6.0V
DDR Memory Termination Regulator
DESCRIPTION
The MP20073 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 2A sink/source tracking
termination regulator. It is specifically designed
for low-cost/low-external component count
systems, where space is a premium.
The MP20073 maintains a fast transient
response only requiring 20µF (2x10µF) of
ceramic output capacitance. The MP20073
supports Kelvin sensing functions.
The MP20073 is available in the 8-pin MSOP
with Exposed PAD package and is specified
from -40oC to 85oC.
