Termination Regulator (DDR3 TR)

Overview

The 3DPM0385-1 is a compact and flexible, Rad Hard by Design, sink/source Termination Regulator for low input voltage, low-noise Double Data Rate (DDR3) memory. The 3DPM0385-1 maintains fast transient response times; offers a remote sensing function; supports control via Command pin and provides all power requirements for DDR VTT bus designs.

By incorporating radiation effect mitigation techniques, the 3DPM0385-1 offers SEL/SET LETth of 60 MeV.cm2/mg and a TID of 75krad(Si).

The 3DPM0385-1 is manufactured with 3D PLUS’s space qualified stacking technology designed for high reliability applications, and is available in a compact, low weight 259-pin BGA package.

Key Features

Source and Sink current capability ±2A
