MCT7812CT 3-Terminal Positive Voltage (12V) Regulator by Motorola.

DESCRIPTION: The MCT7800 Series of 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 fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

Features:
  • Output Voltage: 12V
  • No External Components Required
  • Internal Thermal Overload Protection
  • Internal Short Circuit Current Limiting
  • Output Transistor Safe-Area Compensation
  • Output Voltage Offered with a 4% Tolerance
  • Standard 3-Lead Transistor Package

Picture shows the part. These are in very good condition.
