Description
The FAN1117A and FAN1117A-1.8, -2.5, -2.85, -3.3 and -5
are low dropout three-terminal regulators with 1A 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 specically to be
used in Active Terminators for SCSI bus.
Current limit is trimmed to ensure specied 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 FAN1117A ows into the load, increasing efciency.
The FAN1117A series regulators are available in the
industry-standard SOT-223 and TO-252 (DPAK) power
packages.
