• Manufacturer Part Number: fs1117
• Description: 1.0a Adjustable & Fixed Voltage Ldo Linear Regulator
• Manufacturer: Fortune Semiconductor Corporation

1.
The FS1117 is a series of low-dropout three-terminal
regulators with a dropout of 1.4V at 1A output
current.
The FS1117 series provides current limiting and
thermal shutdown. Its circuit includes a trimmed
bandgap
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 FS1117 has an adjustable version that can
provide the output voltage from 1.25V to 12V with
only two external resistors.
The FS1117 series is available in the industry
standard SOT223 power package.
