Description
The AV1117 and AV1117-2.5, -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 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 AV1117 flows into the load, increasing efficiency.
The AV1117 series regulators are offered in three-pin surface mount package SOT-223.

Note :
1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line
2. Line and load regulation are guaranteed up to the maximum power dissipation. (18W).
Power dissipation is determined by input/output differential and the output current.
Guaranteed maximum output power will not be available over the full input/output voltage range.
