Power Solutions Termination Regulator

Request information

  • TERMINATION REGULATOR

Overview

The DDR2, 3 and 4 Termination Regulator (TR) modules are compact and flexible, Rad-Hard-by-Design for low input voltage, low-noise Double Data Rate (DDR) memories. TR modules maintain fast transient response times; offer a remote sensing function; support control via Command pin and provide all power requirements for DDR VTT bus designs.

By incorporating radiation effect mitigation techniques, they are the perfect solution to be used with DDR memories in high reliability applications.

TR modules are manufactured with 3D PLUS’s Space qualified stacking technology designed for high reliability applications, and is available in a compact, low weight package.

Key features

  • Tightly regulated voltage on VTToutput (JEDEC compatible)

  • Eliminates the need for external output capacitors

  • Source and Sink current capability of ±1A (DDR2 TR) or ±2A (DDR3 TR and DDR4 TR)

  • Radiation Hardened design:

    TID > 50 krad(Si) for DDR2 TR and TID > 100 krad(Si) for DDR3 TR and DDR4 TR

    SEL and SET > 62.5 MeV.cm²/mg

  • Operating temperature -40°C / +105°C

  • Compact footprint with

    24-SOP (DDR2 TR)

    127-BGA (DDR2 TR)

    259-BGA package (DDR3 TR and DDR4 TR)
