| Market Reality | The LM317 has been the default adjustable linear regulator since the 1970s and remains in continuous production across TI, ST, onsemi and a long clone list. The confusion is all in the suffix: LM317, LM317T, LM317L and LM317M are the same regulator design at different packages and current limits, and the modern surface-mount sockets are usually filled by SOT-223 clones such as the AMS317. Where a rail needs more than the 1.5A a TO-220 LM317 can pass, the family ladder (LM350 at 3A, LM338 at 5A) is the correct answer - with a lower output-voltage ceiling as the trade. | - |
