Product details

DDR termination regulator for the 5 V rail

The Texas Instruments TPS51100DGQ is a single-output DDR termination regulator designed to convert a 4.75 V to 5.25 V input rail into a programmable output from 1.2 V to 3.6 V. It is explicitly built for DDR memory termination (VTT) in converter applications, not a general-purpose step-down converter. The 10-HVSSOP package keeps the footprint small for dense memory power layouts.

Input and output — what drives the BOM fit

Input range is 4.75 V to 5.25 V; output range is 1.2 V to 3.6 V.

Temperature grade and environment

Rated for -40°C to 85°C, this part suits industrial control, telecom infrastructure, and outdoor networking gear. It is not qualified to AEC-Q100, so it is not the pick for under-hood automotive or engine-bay environments where extended temperature and vibration specs are required.

Lifecycle and sourcing

The TPS51100DGQ carries an Active lifecycle status with ROHS3 compliance. Availability and pricing confirmed at quote time.

Frequently asked questions

Can TPS51100DGQ be used for DDR4?

Yes, the output can be set to 1.2 V, which is the VTT level for DDR4 termination. The part is a DDR converter regulator, so it is suited for DDR4 memory power.

What is the difference between TPS51100DGQ and TPS51100DGQR?

The difference is packaging: TPS51100DGQ ships in a Tube, while the DGQR suffix typically indicates Tape & Reel packaging. Electrically they are identical.

What is the closest functional second-source to TPS51100DGQ?

The TPS53317RGBR is a peer DDR converter from TI with a single output, but it operates from a 1.0 V input supply and uses the D-CAP+ control scheme. It is not a pin-for-pin replacement — verify the pinout and compensation before substituting.
