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.
