JSR - connected as a 3-pin regulator - stupid question

[MacMiniHiFi]

Hi P-A,
As the gnd is shared on the in- and output on your JSR's can I use them as 3-pin regulator substitutes? Where is the better point to make the gnd connection?
Thanks,
Nic

It should work and you should let the incoming ground be the ground connection.
