Description for the TPS51200

The TPS51200 device is a sink and source double data rate (DDR)termination regulator specifically designed for low input voltage, low-cost, low-noise systemswhere space is a key consideration.

The TPS51200 maintains a fast transient response and requires aminimum output capacitance of only 20 µF. The TPS51200 supports a remotesensing 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 tomonitor the output regulation and an EN signal that can be used to discharge VTT during S3 (suspendto RAM) for DDR applications.

The TPS51200 is available in the thermally efficient 10-pin VSONthermal pad package, and is rated both Green and Pb-free. It is specified from –40°C to+85°C.
