DESCRIPTION
AIC1383 linear regulator is designed to achieve
1.5A source and sink current while regulating
an output voltage to within 25mV.
AIC1383 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 AIC1383 against fault
conditions.
