Parameter	AMS1117-5.0	AMS1117-5.0	Engineering note
Fixed-output accuracy	+/-1.5% maximum	+/-2% maximum	At 5.0 V the target tolerance is +/-100 mV; validate the wider window in the application.

FAE documentary review accepted with a tolerance delta: the unsuffixed exact order code maps to SOT-223 in both manufacturer ordering tables. Both are 5.0 V, 1 A, 1.2 V typical dropout and -40 to +125 C junction range with the same pinout. UMW specifies +/-2% output accuracy versus +/-1.5% for the source, so the wider tolerance must be acceptable in the target design. Not bench-tested.
