DescriptionThe TPS51200 deviceisa sink and source double
data rate (DDR) termination regulator specifically
designed for low input voltage, low-cost, low-noise
systems where spaceisa key consideration.
The TPS51200 maintainsa fast transient response
and requiresa minimum output capacitanceof μF. The TPS51200 supportsa remote sensing
function andall power requirements for DDR, DDR2,
DDR3, DDR3L, Low-Power DDR3 and DDR4
bus termination. addition, the TPS51200 provides an open-drain
PGOOD signalto monitor the output regulation EN signal that can be usedto discharge
during S3 (suspendto RAM)for DDR applications.
Theis available in the thermally efficient 10-pin
VSON thermal pad package, andis rated both Green
and Pb-free.Itis specified from –40°Cto +85°C.
Device Information(1)(1) Forall available packages, see the orderable addendum
the endofthe data sheet.
