Description

The TPS51200 is a sink and source double data rate (DDR) termination regulator designed for low input voltage, low-cost, low-noise systems where space is limited.

Features

• Input Voltage: Supports 2.5-V Rail and 3.3-V Rail
• VLDOIN Voltage Range: 1.1 V to 3.5 V
• Sink and Source Termination Regulator Includes Droop Compensation
• Requires Minimum Output Capacitance of 20-μF (Typically 3 × 10-μF MLCCs) for Memory Termination Applications (DDR)
• PGOOD to Monitor Output Regulation
• EN Input
• REFIN Input Allows for Flexible Input Tracking Either Directly or Through Resistor Divider
• Remote Sensing (VOSNS)
• ±10-mA Buffered Reference (REFOUT)
• Built-in Soft Start, UVLO, and OCL
• Thermal Shutdown
• Supports DDR, DDR2, DDR3, DDR3L, LowPower DDR3, and DDR4 VTT Applications
• 10-Pin VSON Package With Thermal Pad

Applications

• Memory Termination Regulator for DDR, DDR2,DDR3, DDR3L, Low-Power DDR3 and DDR4
• Notebooks, Desktops, and Servers
• Telecom and Datacom
• Base Stations
• LCD-TVs and PDP-TVs
• Copiers and Printers
• Set-Top Boxes

Comparison

• Supports a variety of DDR-related applications and voltage ranges
• Fast transient response
• Requires small output capacitance for memory termination applications

• Designed for only low input voltage applications
• May not be cost-effective for larger systems
