Description

The UR5512 is a linear regulator which provides up to 2 Amp bi-directional driving and sinking capability for DDR SDRAM bus terminator application. The output termination voltage of UR5512 tracks the reference voltage applied at VREF pin. A resistor divider connected to VIN, GND and VREF pins is used to force a reference voltage to VREF pin.

The UR5512 contains a high-speed operational amplifier to provide excellent response to line/load transient. An active-low shutdown (VREF) pin provides Suspend to RAM (STR) functionality. Additional features include current limiting protection, on-chip thermal shut-down protection.
