The FL1117-XX is a low-dropout three-terminal regulator with 1.0A output current ability, and the dropout voltage is specified at typical 1.1V at 1.0A current load decreasing at lower load currents.
The FL1117-XX is optimized for low voltage where transient response and minimum input voltage are critical. It provides current limit and thermal shutdown protection solutions. Its circuit includes a trimmed band gap reference to assure output voltage accuracy to be within ±1%.On-chip thermal shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction temperature.
The FL1117-XX is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V fixed-output voltage versions and ADJ output voltage version. The fixed versions integrate the adjust resistors.
The FL1117-XX is available in the industry-standard SOT-223 package.
