描述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.Theis 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.特性 Input Voltage: Supports 2.5-V Rail and 3.3-V Rail VLDOIN Voltage Range: 1.1 V to 3.5 VSink and Source Termination Regulator Includes Droop CompensationRequires Minimum Output Capacitance of 20-µF (Typically 3 × 10-µF MLCCs) forMemory Termination Applications (DDR)PGOOD to Monitor Output RegulationEN Input REFIN Input Allows for Flexible Input Tracking Either Directly or Through ResistorDividerRemote Sensing (VOSNS)±10-mA Buffered Reference (REFOUT)Built-in Soft Start, UVLO, and OCLThermal ShutdownSupports DDR, DDR2, DDR3, DDR3L, Low-Power DDR3, and DDR4 VTTApplications 10-Pin VSON Package With Thermal PadAll trademarks are the property of their respective owners.
