DESCRIPTION
The MP20073 integrates the DDR memory termination regulator with the output voltage (VTT) and a buffered VTTREF whose output is 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 20uF (2x10uF) 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 −40°C to 85°C.
