3 Description

The TPS51200 device is a sink and source double

data rate (DDR) termination regulator specifically

designed for low input voltage, low-cost, low-noise

systems where space is a key consideration.

The TPS51200 maintains a fast transient response

and requires a minimum output capacitance of only

20 μF. The TPS51200 supports a remote sensing

function and all power requirements for DDR, DDR2,

DDR3, DDR3L, Low-Power DDR3 and DDR4 VTT

bus termination.

In addition, the TPS51200 provides an open-drain

PGOOD signal to monitor the output regulation and

an EN signal that can be used to discharge VTT

during S3 (suspend to RAM) for DDR applications.
