FAN1086
1.5A Adjustable/Fixed Low Dropout Linear Regulator
• Low dropout voltage
• Load regulation typical
• Trimmed current limit
• On-chip thermal limiting
• Standard SOT-223, TO-263, and TO-252 packages
• Three-terminal adjustable or 2.5V, 2.85V, 3.3V, 5V
• Active SCSI terminators
• High linear regulators
• Post regulators for switching supplies
• Battery chargers
• 5V to 3.3V linear regulators
• Motherboard clock supplies

The FAN1086 and FAN1086-2.5, 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 to be used in Active Terminators for SCSI bus.

Current limit is trimmed to ensure 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 into the load, increasing

The FAN1086 series regulators are available in the industrystandard SOT-223, TO-263, and TO-252 power packages.
