Description

The FAN1589 is a low dropout three-terminal regulator with

2.7A output current capability. This device has been optimized

mum input voltage are critical. The FAN1589 offers fixed

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 FAN1589 is available in the industry-standard TO-220,

TO-263, TO-263 center cut and TO-252 (DPAK) power

packages.
