LM341/LM78MXX Series 3-Terminal Positive Voltage
Regulators
General Description
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
n Output current in excess of 0.5A n No external components n Internal thermal overload protection n Internal short circuit current-limiting n Output
transistor safe-area compensation n Available in TO-220, TO-39, and TO-252 D-PAK
packages n Output voltages of 5V, 12V, and 15V
