DESCRIPTION

The LM1589 is a low dropout three-terminal regulator with 2.7A output current capability.

This device has been optimized for V TT bus termination, where transient response and mini-mum

input voltage are critical.

The LM1589 offers fixed 1.2V with 2.7A current capability for a GTL+ bus V TT termination.

Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip

thermal limiting pro-vides protection against any combination of overload and ambient temperature

that would create excessive junction temperatures.

The LM1589 is available in the industry-standard TO-220, TO-263 power packages.
