Termination Regulator (DDR3 TR)
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.
Source and Sink current capability ±2A
Output voltage (VTT) regulated to VREF_IN
Reference voltage is set externally (VREF_IN)
Reference voltage is buffered inside the module (VREF_OUT)
Remote VTT voltage sensing (VTT_SENSE)
An Enable command is used to put VTT output in high impedance state (Suspend-to-RAM mode)
Eliminates the need for external output capacitors
Tightly regulated voltage on VTT output
