ON Semiconductor's 12-volt linear voltage regulator comes under the MC7812 family. These products are monolithic integrated circuits designed as fixed-voltage regulators for a wide range of applications including local, on-card regulation. The positive 7812 voltage regulator requires no external components and incorporates internal thermal overload protection and current limiting plus safe area compensation. There is no need for external components although it is possible to adjust the voltage and current with external devices.

Features and Benefits
• Internal thermal overload protection
• Internal short circuit current limiting
• Output transistor safe – area compensation
• These are Pb-Free devices
• Output current in access of 1A
• Output Voltage Offered in 1.5%, 2% and 4% Tolerance
• Package type: TO-220
• Accuracy +4%

Applications
Linear regulators are simple voltage regulator circuits commonly adopted in electronics. A Linear voltage regulator uses a closed feedback loop to bias a pass element to maintain a steady voltage across output terminals. Linear regulators are most commonly highly integrated, which include the pass element and feedback loop.
