DESCRIPTION

AIC1387 linear regulator is designed to deliver 2A continuous current while regulating an output voltage to within b20mV and up to 3A peak transient currents for termination of DDR / DDRII / DDRIII. And it can deliver 1.5A continue current for termination of DDRIV.
AIC1387 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 highspeed 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 AIC1387 is available in the SOP-8 and SOP-8E package
