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 bination 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...
