  LM341,LM78M05,LM78M12,LM78M15 LM341/LM78MXX Series 3-Terminal Positive Voltage Regulators  Literature Number: SNVS090E  LM341/LM78MXX Series3-Terminal Positive Voltage Regulators General Description The LM341 and LM78MXX series of three-terminal positivevoltage regulators employ built-in current limiting, thermalshutdown, and safe-operating area protection which makesthem virtually immune to damage from output overloads.With adequate heatsinking, they can deliver in excess of0.5A output current. Typical applications would include local(on-card) regulators which can eliminate the noise and de-graded 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-PAKpackages n Output voltages of 5V, 12V, and 15V Connection Diagrams TO-39 Metal Can Package (H) 01048405 Bottom ViewOrder Number LM78M05CH, LM78M12CH or LM78M15CHSee NS Package Number H03ATO-220 Power Package (T) 01048406 Top ViewOrder Number LM341T-5.0, LM341T-12, LM341T-15, LM78M05CT, LM78M12CT or LM78M15CTSee NS Package Number T03BTO-252 01048419 Top ViewOrder Number LM78M05CDTSee NS Package Number TD03B August 2005 L M 3 4  1   /   L M7  8  MX X  S  er  i    e s 3 - T  er  mi   n al   P  o si    t   i   v eV  ol    t    a  g eR  e  g ul    a t    or   s  © 2005 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 Office/ Distributors for availability and specifications.
