3 Description
The TPS51200-Q1 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-Q1 device maintains a fast transient
response and only requires a minimum output
capacitance of 20 μF. The TPS51200-Q1 device
supports a remote sensing function and all power
requirements for DDR, DDR2, DDR3, and Low Power
DDR3 and DDR4 VTT bus termination.
In addition, the TPS51200-Q1 device 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-Q1 device is available in the
thermally-efficient VSON-10 package, and is rated
both green and Pb-free. The device is specified from
–40°C to 125°C.
