LM78M05 - 3-Terminal Positive Voltage Regulators
Datasheet Packaging Samples & Pricing Reliability Knowledge Base

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

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. More...

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.

Reliability Metrics

LM78M05CDTSLM04404600353250011002356520

LM78M05CTSLM04404600353250011002356520

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
