Fast transient response
Low dropout voltage at up to 2.7A

Trimmed current limit
On-chip thermal limiting
Standard TO-220, TO-263, TO-263 center cut and
TO-252 (DPAK) packages
Description
The FAN1589 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 FAN1589 offers 鏗亁ed
1.2V with 2.7A current capability for a GTL+ bus V
TT
termination.
Current limit is trimmed to ensure speci鏗乪d 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.
