TECHNICAL DATA
2.7 A Low Dropout Positive Regulator
IK1589
Description
The IK1589 is a low dropout three-terminal
regulator with 2.7A output current capability. This
device has been optimized for VTT bus termination,
where transient response and minimum input voltage
are critical. The IK1589 offers fixed 1.2V with 2.7A
current capability for a GTL+ bus VTT termination.
Current limit is trimmed to ensure specified output
current and controlled short-circuit current. On-chip
thermal limiting provides protection against any
combination of overload and ambient temperature that
would create excessive junction temperatures.
The IK1589 is available in the industry-standard
TO-220, TO-263-3L, TO-263-2L and TO-252 (DPAK)
power packages.
