MC7812: Linear Voltage Regulator, Positive, 12 V, 1.0 A

These linear voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and safe-area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.

Features
  • Output Current in Excess of 1.0 A
  • No External Components Required
  • Internal Thermal Overload Protection
  • Internal Short Circuit Current Limiting
  • Output Transistor Safe-Area Compensation
  • Output Voltage Offered in 1.5%, 2% and 4% Tolerance
  • Pb-Free Packages are Available
Applications
  • Available in Surface Mount D 2 PAK and Standard 3-Lead Transistor Packages
