3 Description

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.
