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
