... General Description The FS1117 is a series of low-dropout three-terminal regulators with a dropout of 1. output current. The FS1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output 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– ...

... This is summarized in the above equation. Since the minimum load current requirement of be FS1117 is 10mA typically selected to be 121Ω resistor so that it automatically satisfies the minimum requirement . Notice that since ladj is typically in the range and should only be considered when a very precise output voltage setting is required ...
