LM341/LM78MXX Series 3-Terminal Positive Voltage Regulators July 1999 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 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 n Output voltages of 5V, 12V, and 15V n n n n n n Connection Diagrams TO-39 Metal Can Package (H) DS010484-5 Bottom View Order Number LM78M05CH, LM78M12CH or LM78M15CH See NS Package Number H03A TO-220 Power Package (T) DS010484-6 Top View Order Number LM341T-5.0, LM341T-12, LM341T-15, LM78M05CT, LM78M12CT or LM78M15CT See NS Package Number T03B TO-252 DS010484-19 Top View Order Number LM78M05CDT See NS Package Number TD03B © 1999 National Semiconductor Corporation DS010484 www.national.com Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Of...
