G2995 G2996 台湾致新代理商 GMT LDO系列 DDR终结器

DDR Termination Regulator

General Description
The  G2995  is  a  linear  regulator  designed  to  meet  the  JEDEC SSTL-2 and SSTL-3 (Series Stub Termination Logic)  specifications  for  termination  of  DDR-SDRAM.  It contains a high-speed operational amplifier that pro-vides  excellent  response  to  the  load  transients.  This  device  can  deliver  1.5A  continuous  current  and  tran-sient peaks up to 3A in the application as required for DDR-SDRAM termination. With an independent VSENSEpin,  the  G2995  can  provide  superior  load  regulation.  The G2995 provides a VREF output as the reference for the applications of the chipset and DIMMs.

The  G2995  can  easily  provide  the  accurate  VTT  and  VREF  voltages  without  external  resistors  that  PCB  ar-eas  can  be  reduced.  The  quiescent  current  is  as  low  as  280μA  @  2.5V.  So  the  power  consumption  can  meet the low power consumption applications.
