Looks indeed very strange. The ground pin is at the output, the output together with the power supply pin, stabilized via a zener diode?

Maybe it's an other chip? Where is it from?

Hello,

I see no problems with the schematic.
When you look at the internal schematic of the 311, you see that 7 is the collector of the output transistor and 1 is the (current limited) emittor output.
