General Description

The FS1084 is a series of low dropout three-terminal regulators with a dropout of 1.5V at 1Aoutput current.
The FS1084 series provides current limiting and thermal shutdown. Its circuit includes a trimmed band gap reference to assure output voltage accuracy to be within 2% for 1.8V, 3.3V and adjustable versions. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature.
The FS1084 has an adjustable version that can provide the output voltage from 1.25V to 12V with only two external resistors.
The FS1084 series is available in the industry standard TO263-3L power package.
