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, DDR3L, 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.
