2A, 1.3V–6.0V DDR Memory Termination Regulator AEC-Q100 Qualified



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.
