Needs validationhigh risk
LM317 may replace a 5V regulator only with circuit changes and FAE review.
Best Alternatives to L7805CV
L7805CV is a 5V fixed positive TO-220 regulator. The listed candidates do not show a verified pin-compatible replacement.

Can it be replaced directly?
Direct replacement for L7805CV should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use another 5V 78xx regulator only after pinout and ratings are checked; LM317 is redesign-only.
Main risk
Wrong output voltage or unverified pinout can damage a 5V rail.
