2A, DDR Termination Regulator



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 -40 degree C to 85 degree C.
