鈥?/div>
Fast transient response
Low dropout voltage at up to 3A
Load regulation: 0.05% typical
Trimmed current limit
On-chip thermal limiting
Standard TO-220, TO-263, TO-263 center cut,
and TO-252 packages
Description
The FAN1587A, FAN1587A-1.5, and FAN1587A-3.3 are low
dropout three-terminal regulators with 3A output current capa-
bility. These devices have been optimized for low voltage
applications including V
TT
bus termination, where transient
response and minimum input voltage are critical. The
FAN1587A is ideal for low voltage microprocessor applica-
tions requiring a regulated output from 1.5V to 3.6V with an
input supply of 12V or less. The FAN1587A-1.5 offers 鏗亁ed
1.5V with 3A current capability for GTL+ bus V
TT
termina-
tion. The FAN1587A-3.3 offers 鏗亁ed 3.3V current capability
for logic IC operation.
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 FAN1587A, FAN1587A-1.5, and FAN1587A-3.3 are
available in the industry-standard TO-220, TO-263, TO-263
center cut, and TO-252 (DPAK) power packages.
