TYPICAL APPLICATION CIRCUIT
AIC1383B
3A Termination Regulator
DESCRIPTION
AIC1383B linear regulator is designed to
achieve 3A source and sink current while
regulating an output voltage to within 45mV.
AIC1383B converts voltage supplies range
from 1.6V to 6V into an output voltage that
adjusts by two external voltage divider
resistors. It provides an excellent voltage
source for active termination schemes of high-
speed transmission lines as those seen in
high-speed memory buses, and it meets the
JEDEC SSTL-2 and SSTL-3 specifications for
termination of DDR-SRAM.
Built-in current limiting in source and sink
mode, with thermal shutdown provide
maximal protection to the AIC1383B against
fault conditions.
