Texas Instruments TPS51200DRCT DDR Termination Regulator, 3A, VSON-10
Texas Instruments TPS51200DRCT DDR termination regulator: 3A sink/source, 1.1-3.5V, VSON-10. Supports DDR, DDR2, DDR3 & DDR4 VTT.
The Texas Instruments TPS51200DRCT is a sink/source Double Data Rate (DDR) termination regulator, designed for low input voltage, low-noise systems where space is a key consideration. It maintains a fast transient response and requires only a minimum output capacitance of 20 µF, typically three 10 µF multilayer ceramic capacitors (MLCCs), simplifying your power design.
This regulator supports a VLDOIN voltage range from 1.1 V to 3.5 V, making it versatile for a variety of applications. It provides a sink/source termination function with built-in droop compensation, ensuring stable and accurate VTT bus termination. The device includes a remote sensing function (VOSNS) and a ±10 mA buffered reference (REFOUT) for flexible output tracking.
Key features
- Open-drain PGOOD signal for output regulation monitoring
- EN input for enabling and discharging VTT during S3 (suspend to RAM) in DDR applications
- REFIN input allows flexible input tracking, either directly or through a resistor divider
- Built-in soft start, under-voltage lockout (UVLO), over-current limit (OCL) and thermal shutdown for comprehensive protection
The TPS51200DRCT meets JEDEC specifications for DDR, DDR2, DDR3 and low-power DDR3/DDR4 VTT bus termination, ensuring reliable performance in memory power applications. Housed in a compact VSON-10 package, it is ideal for space-constrained designs in computers, peripherals, networking and consumer electronics.
