UR6517
LINEAR INTEGRATED CIRCUIT
1.8A DDR BUS TERMINATION REGULATOR
DESCRIPTION
The UR6517 is a linear regulator providing up to 1.8A transient current sourcing and sinking capability for DDR bus terminator applications while regulating an output voltage to within 20mV. It contains a high speed operational amplifier which provides fast load transient response and only requires 10uF of ceramic output capacitance.
The UR6517 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.
