UR5512
LINEAR INTEGRATED CIRCUIT
2A DDR BUS TERMINATION REGULATOR
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 VREF pin.
A resistor divider connected to VIN, GND and VREF pins is used to force a reference
voltage to VREF pin.
The UTC 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 protectio...
