Typical Applications
TPS51200DRCR is suitable for 6 applications: DDR Memory Termination, Telecom and Datacom Equipment, LCD-TV and PDP-TV, Copier and Printer, Set-Top Box, GSM Base Station.
DDR Memory Termination
The TPS51200DRCR provides the VTT rail for DDR, DDR2, DDR3, DDR3L, and DDR4 memory systems. Its 3A sink/source capability and fast transient response ensure stable termination voltage at half VDDQ, critical for signal integrity in high-speed memory buses. The device's low output capacitance requirement (20Β΅F) simplifies layout, and remote sensing compensates for PCB trace drops, making it ideal for notebooks, desktops, and servers.

Key Differentiators
- Automotive-grade variant available (vs TPS51200QDRCRQ1)
- Low minimum output capacitance (20Β΅F) (vs TPS51206DRCR)
- Cross-brand availability (vs RT8120B)
Design Notes
For optimal performance, place the output capacitors (minimum 20Β΅F) as close to the VO pin as possible to minimize parasitic inductance. Use short, wide traces for the high-current VTT path to reduce voltage drops. The remote sense pins (VDDQSNS and VOSNS) should be connected directly to the termination point to ensure accurate regulation.
The TPS51200DRCR can dissipate significant power when sourcing or sinking 3A. Ensure adequate copper area on the PCB for heat dissipation, especially in high-temperature environments. The VSON package has an exposed thermal pad; connect it to a large ground plane to improve thermal performance. Monitor junction temperature to avoid thermal shutdown.
Do not exceed the input voltage range of 6V. Ensure the enable pin is properly driven; floating it may cause unpredictable operation. The VTTREF output should be buffered if used to drive multiple loads. Avoid placing the output capacitors too far from the IC, as this can cause instability. Always verify the pinout with the datasheet before layout.
Compliance Information
RoHS compliant per TI product page. Not AEC-Q100 qualified; use TPS51200QDRCRQ1 for automotive.
