DDR Termination Voltage Supply - supports

The SS6383 linear regulator is designed to

provide 1.5A source and sink current while

regulating an output voltage to within 25mV.

The SS6383 converts voltage supplies ranging

from 1.6V to 6V into an output voltage that

is set by two external voltage-divider resistors.

It provides an excellent voltage source for

active termination schemes for high-speed

transmission lines such as those seen in high-

speed memory buses.

The built-in current-limiting in source and sink

mode, together with thermal shutdown, provides

maximum protection to the SS6383 against

fault conditions.
