The LM341 and LM78M05 three-pin positive voltage regulators employ built-in current limiting, thermal shutdown, and safe-operating area protection, which makes them virtually immune to damage from output overloads.

With adequate heat sinking, they can deliver in excess of 0.5-A output current. Typical applications would include local (on-card) regulators which can eliminate the noise and degraded performance associated with single-point regulation.
