General Description
The  G2986  is  a  3A  sink/source  tracking  termination  regulator.   It   is   specifically   designed   for   low-cost/   low-external  component  count  systems.  The  G2986  maintains  a  high  speed  operational  amplifier  that  pro-vides  fast  load  transient  response  and  only  requires  20μF  (2×10μF)  of  ceramic  output  capacitance.  The  G2986 supports remote sensing functions and all fea-tures  required  to  power  the  LPDDR2  /LPDDR3  /DDR  IIIL  VTT  bus  termination  according  to  the  JEDEC  specification.  In  addition,  the  G2986  includes  inte-grated  sleep-state  controls  placing  VTT  in  High-Z  in  S3   (suspend   to   RAM)   and   soft-off   for   VTT   and   VTTREF in S5 (Shutdown). The G2986 is available in the thermally efficient TDFN2X2-10.
