FAN1086
1.5A Adjustable/Fixed Low Dropout Linear Regulator
Features
•
•
•
•
•
•
Low dropout voltage
Load regulation: 0.05% typical
Trimmed current limit
On-chip thermal limiting
Standard SOT-223, TO-263, and TO-252 packages
Three-terminal adjustable or fixed 2.5V, 2.85V, 3.3V, 5V
Description
The FAN1086 and FAN1086-2.5, -2.85, -3.3 and -5 are low
dropout three-terminal regulators with 1.5A output current
capability. These devices have been optimized for low voltage
where transient response and minimum input voltage are
critical. The 2.85V version is designed specifically to be
used in Active Terminators for SCSI bus.
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 temperatures that would create excessive junction
temperatures.
Unlike PNP type regulators where up to 10% of the output
current is wasted as quiescent current, the quiescent current
of the FAN1086 flows into the load, increasing efficiency.
The FAN1086 series regulators are available in the industry-
standard SOT-223, TO-263, and TO-252 power packages.
