DESCRIPTION

VTT Termination Regulator

The TPS51206 is a sink/source double date rate

(DDR) termination regulator with VTTREF buffered

reference output. It is specifically designed for low

input voltage, low cost, low external component count

systems where space is a key consideration. The

TPS51206 maintains fast transient response and only

requires 1 × 10-µF of ceramic output capacitance.

The TPS51206 supports a remote sensing function

and all power requirements for DDR2, DDR3 and

Low-Power DDR3 (DDR3L) VTT bus. The VTT

current capability is ±2A peak. The TPS51206

supports all of the DDR power states, putting VTT to

High-Z in S3 state (suspend to RAM) and discharging

VTT and VTTREF in S4/S5 state (suspend to disk).
