Texas Instruments  PTPS51200AQDRCRQ1

The TPS51200A-Q1 device is a sink and source double-data-rate (DDR) termination regulatorspecifically designed for low input voltage, low-cost, low-noise systems where space is a keyconsideration.

The device maintains a fast transient response and only requires a minimum outputcapacitance of 20 µF. The device supports a remote sensing function and all power requirements forDDR, DDR2, DDR3, and Low Power DDR3 and DDR4 VTT bus termination.

In addition, the device provides an open-drain PGOOD signal to monitor the outputregulation and an EN signal that can be used to discharge VTT during S3 (suspend to RAM) for DDRapplications.

The device is available in the thermally-efficient VSON-10 package, and is rated bothgreen and Pb-free. The device is specified from –40°C to 125°C.
