DESCRIPTION
The MP20075 precision DDR2/3/3L/4 termination LDO regulator features a precision VREF/2 tracking voltage for accurate termination. The VTT-LDO output can sink/source up to 3A.
The MP20075 maintains a fast transient response only requires 20μF (2x10μF) ceramic output capacitance. The MP20075 supports Kelvin sensing.
The MP20075 is available in the 8-pin MSOP with Exposed PAD and is specified from −40°C to 85°C.
