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.
