General Description
The FAN1589 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 FAN1589 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 FAN1589 is available in the industry-standard TO-220, TO-263, TO-263 center cut and TO-252 (DPAK) power packages.
