DESCRIPTION

The MPQ20073 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 MPQ20073 maintains a fast transient

response only requiring 20μF (2x10μF) of

ceramic output capacitance. The MPQ20073

supports Kelvin sensing functions.

The MPQ20073 is available in the 8-pin MSOP

with Exposed PAD package.
