SS6383 Datasheet, PDF (1/7 Pages) Silicon Standard Corp. – 1.5A DDR Termination Regulator

SS6383(G)
1.5A DDR Termination Regulator
FEATURES
DESCRIPTION
Source and sink current capability of 1.5A
Low output voltage offset, ±20mV
High accuracy output voltage at full-load
The SS6383 linear regulator is designed to
provide 1.5A source and sink current while
regulating an output voltage to within 25mV.
VOUT adjustable by external resistors
Low external component count
Current limit protection
Thermal protection
SO-8 package
APPLICATIONS
Mother Board
Graphic Cards
DDR Termination Voltage Supply - supports
DDR1 (1.25VTT), DDR2 (0.9VTT), and meets
JEDEC SSTL-2 and SSTL-3 term. specifications
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.
