AIC1383B General 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.
