3 Description
The TPS51200-EP 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-EP maintains a fast transient
response and only requires a minimum output
capacitance of 20 μF. The TPS51200-EP supports a
remote sensing function and all power requirements
for DDR, DDR2, DDR3, Low-Power DDR3, and
DDR4 VTT bus termination.
In addition, the TPS51200-EP 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.
The TPS51200-EP is available in the thermally
efficient 10-pin VSON thermal pad package, and is
rated both Green and Pb-free. It is specified from
–55°C to +125°C.
