Description

The LM341 and LM78M05 three-pin 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 heat sinking, they can deliver in excess of 0.5-A 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 0.5 A
  • No External Components
  • Internal Thermal Overload Protection
  • Internal Short Circuit Current-Limiting
  • Output Transistor Safe-Area Compensation
  • Available in 3-Pin TO-220, TO-252, and TO packages
  • Output Voltages of 5 V and 15 V
