TPS51518RUKR

Description
The TPS51206 device is a sink and 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 device maintains fast transient response and only requires 1 × 10-µF of ceramic output capacitance.
The device supports a remote sensing function and all power requirements for DDR2, DDR3 and Low-Power DDR3 (DDR3L), and DDR4 VTT bus.
The VTT current capability is ±2-A peak.
The device 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 or S5 state (suspend to disk).
