The TPS51200DRGR from Texas Instruments is a high-precision, sink/source double data rate (DDR) termination regulator specifically designed for low-input voltage, low-cost, and low-noise systems where space is a key consideration. This device maintains fast transient responses and only requires a minimum output capacitance of 20μF. The small form factor and high level of integration make the TPS51200DRGR an ideal choice for various applications, including notebook computers, desktops, graphics cards, memory modules, and other computing and memory applications.

Key Features

• Supports DDR2, DDR3, DDR3L, and DDR4 memory systems.
• Bi-directional synchronization with the host's switching frequency.
• Source and sink current capability.
• Low quiescent current of 3 mA typical in active mode.
• Integrated VTTREF buffered reference output.
• Thermal shutdown protection.
• Adjustable output voltage and soft-start.
• Available in a 10-pin VSON package with a thermal pad.

Performance Specifications

The TPS51200DRGR is engineered to provide a termination voltage that is half the DDR memory supply voltage VDDQ. This is critical for stabilizing the bidirectional data bus lines during read and write operations. With an input voltage range of 1.1 V to 3.5 V, the device can operate efficiently across various system voltages. Its sink/source current capability ensures stable operation under dynamic loading conditions.

Applications

Due to its versatility and reliability, the TPS51200DRGR is suited for a wide range of applications beyond traditional computing systems. It can also be used in servers, embedded systems, and industrial computing devices that require a stable and efficient power supply for their memory termination needs.
