hi,
Do you have this drawing?
Dim between adjacent pins on the same row is 0.1inch.
Dim between rows is 0.2inch
So it should fit into standard pcb at 0.1inch pitch.
If you want to plug it into a project breadboard you will have to solder it to a header,, if you draw lots of current thru your breadboard you could melt the plastic near the pin/sockets.
If you dont have an header, solder, solid 0.2mm dia wire to each pin and plug these into the project board...or mount the LM on a piece of pcb and run wires from the LM/pcb to the project board.
