Product Description

The MP20075 precision DDR2/3/3L 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 degree C to 85 degree C.

3A, 1.30V-3.6V DDR Memory VTT Termination Regulator

The MP20075 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 3A sink/source tracking termination regulator. It is specifically designed for low-cost/low-external component count systems, where space is a premium.

The MP20075 maintains a fast transient response only requiring 20uF (2x10μF) of ceramic output capacitance. The MP20075 supports Kelvin sensing functions.

The MP20075 is available in the 8-pin MSOP with Exposed PAD, package and is specified from −40oC to 85oC.
