Preliminary
2A SINK & SOURCE
ADJUSTABLE LINEAR BUS
TERMINATOR
DESCRIPTION
The UTC UR6516B is a low cost linear regulator providing a desired
output voltage or termination voltage for various applications by
converting voltage supplies ranging from 1V ~ 6.0V. The desired
output voltage could be programmable by two external voltage divider
resistors.
The UTC UR6516B can source or sink up to 2A of current while
regulating an output voltage to within 2% (DDR-I), 3% (DDR-II) or less.
The UTC UR6516B can be used in applications, such as PCI/AGP
graphics, game/play station, set top box, mother board.
FEATURES
* Ideal for DDR-I ,DDR-II
* Output Voltage could Drop Down to 0.6V
* Source and Sink up to 2A, Without an External Heat Sink
* Integrated Power MOSFETs
* Output Voltage Varies though Adjusting External Resistors
* ICCQ is Lower than 500uA at VCCA
* Thermal Shutdown Protection, Current Limit Protection, and Short
Circuit Protection Circuits Included
* Shutdown for Standby or Suspend Mode Operation
* Requiring Minimum External Components

Preliminary
CMOS IC
FUNCTIONAL DESCRIPTION
The UTC UR6516B is a low cost linear regulator, which can sink and source 2A of current without an external heat
sink.
The UTC UR6516B incorporates power MOSFETs that are capable of sourcing and sinking 2A of current while
keeping perfect voltage regulation. By using the external feedback, the output voltage can be regulated within 3% or
less. Separate voltage supply inputs have been added to fit applications with various power supplies for the databus
and power buses.
OUTPUTS
The VOUT pins (output voltage pins) are connected to the databus, address, or clock lines via an external inductor.
The output voltage varies depending on the input voltage.
INPUTS
The output voltage is determined by the input voltage. The desired output voltage could be programmable by two
external voltage divider resistors.
The VIN pin is suggested to connect to VDDQ of memory module for better tracking with memory VDDQ.
OTHER SUPPLY VOLTAGES
VCCA provide the voltage supply to the logic section and internal error amplifiers of UTC UR6516B.
