UR5512

DESCRIPTION

The UTC 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 tracks the

reference voltage applied at V REF pin. A resistor divider connected to

V IN , GND and V REF pins is used to force a reference voltage to V REF

pin.

The UTC UR5512 contains a high-speed operational amplifier to

provide excellent response to line/load transient. An active-low

shutdown (V REF ) pin provides Suspend to RAM (STR) functionality.

Additional features include current limiting protection, on-chip

thermal shut-down protection.

 FEATURES
