Do not trust the old 1990s scans. Get the new schematic, rework your PCB layouts, and enjoy accurate, isolated current sensing once again.
(Note: Always verify the specific datasheet for your package variant, as SOT-23 pinouts differ from SIP-3). lah103p schematic new
Now, you need the schematic to fix it.
