The UTC UR5516 is designed to provide a regulated voltage with

bi-directional output current for DDR-SDRAM termination.

Current-limit work to limit the short-circuit current, on-chip thermal

shutdown provides protection against any combination of overload

that would create excessive junction temperature. The output voltage

pin. In addition, an external ceramic capacitor and an open-drain

the output. The output of UTC UR5516 will be high impedance after
