DESCRIPTION
AIC1386 linear regulator is designed to achieve 2A source and sink current for termination of. DDR / DDRII / DDRIII while regulating an output voltage to within ±20mV. And it can deliver 1.5A continue current for termination of DDRIV.
AIC1386 converts voltage supplies range from 1.1V to 5.5V 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 double data rate (DDR) memory system, and it meets the JEDEC SSTL-2 and SSTL-18 or other specific interfaces such as HSTL, SCSI-1 and SCSI-3 specifications for termination of DDR-SRAM.
Built-in current limiting in source and sink mode, on-chip thermal shutdown protection to against fault conditions.
The AIC1386 is available in the SOP-8E package
