2A DDR BUS TERMINATION REGULATOR
DESCRIPTION
The UR6515C is a linear regulator providing up to 2A transient peak current sourcing and sinking capability for DDR SDRAM bus terminator applications while regulating an output voltage to within 40mV. It contains a high speed operational amplifier which provides
fast load transient response .
The UR6515C 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 the reference voltage to VREF pin.
Additional features include current limiting protection and thermal shutdown protection.
