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 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
* DDR-I and DDR-II termination voltage applications
* Driving and sinking current up to 2A
* Low output voltage offset (within 20mV@±2A)
* Adjustable output voltage by external resistors
* Suspend to RAM (STR) functionality
* Current limiting protection
* Thermal protection
* Cost-effective and easy to use
