The Future of Analog IC Technology
DDR Memory Termination Regulator
The MP20073 integrates the DDR memory
termination regulator with the output voltage
(VTT) and a buffered VTTREF outputs is a half
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.
VDDQ Voltage Range: 1.3V to 6.0 V
Up to 2A Integrated Sink/Source Linear
Regulator with Accurate VREF/2 Divider
Reference for DDR Termination
Requires Only 20µF Ceramic Output
Drive Voltage : 3.3V
1.3V Input (VDDQ) Helps Reduce Total
Integrated Divider Tracks VREF for VTT
