Overview
UNISONIC TECHNOLOGIES CO.
, LTD UR5516A LINEAR INTEGRATED CIRCUIT 3A BUS TERMINATION REGULATOR  DESCRIPTION The UTC UR5516A 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 tracks the voltage at VREF pin.
A resistor divider connected to VIN, GND and VREF pins is used to provide a half voltage of VIN to VREF pin.
In addition, an external ceramic capacitor and an open-drain transistor connected to VREF pin provides soft-start and shu...
