IK1589 Datasheet, PDF (1/9 Pages) IK Semicon Co., Ltd – 2.7 A Low Dropout Positive Regulator

2.7 A Low Dropout Positive Regulator
Description
The IK1589 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 minimum input voltage
are critical. The IK1589 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 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.
