The FSP1117 is a series of low dropout three-terminal
regulators with a dropout of 1.15V at 1A output current.
The FSP1117 series provides current limiting and
thermal shutdown. Its circuit includes a trimmed
bandgap reference to assure output voltage accuracy
to be within 1% for 1.5V, 1.8V, 2.5V, 3.3.V, 5.0V and
adjustable versions or 2% for 1.2V version. 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 FSP1117 has an adjustable version that can
provide the output voltage from 1.25V to 12V with only
two external resistors.
The FSP1117 series is available in the industry
standard TO220-3L, TO263-3L, TO252-2L and
SOT223 power packages.
