- Output current in excess of 0.5 A
- No external components
- Internal thermal overload protection
- Internal short circuit current-limiting

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.
