The LM341 and LM78MXX series of three-terminal 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 heatsinking, they can deliver in excess of 0.5A output current. Typical applications would include local (on-card) regulators which can eliminate the noise and degraded performance associated with single-point regulation.

Features

Output current in excess of 0.5A
No external components
Internal thermal overload protection
Internal short circuit current-limiting
Output transistor safe-area compensation
Available in TO-220, TO-39, and TO-252 D-PAK packages
Output voltages of 5V, 12V, and 15V
