G2986K21U
LPDDR2/LPDDR3/DDR4 Termination Regulator
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 provides fast load transient response and only re-quires 20µF (210µF) of ceramic output capaci-tance. The G2986 supports remote sensing func-tions and all features required to power the LPDDR2 /LPDDR3/DDR4 /DDR 3L VTT bus termi-nation according to the JEDEC specification. In addition, the G2986 includes integrated 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.
