7812 dc Voltage Regulator IC – 12V Fixed Linear Voltage Regulator (TO-220 Package)
The 7812 voltage regulator is a member of the 7800 series of voltage regulators, designed to provide a stable and fixed 12V output from a higher input voltage. It is a linear voltage regulator, similar to the 7805, but with a fixed output of 12V. The 7812 is widely used in electronic circuits that require a 12V power supply for components, such as microcontrollers, sensors, and communication devices. The 7812 voltage regulator IC provides a fixed 12V DC output with up to 1.5A current, ideal for power supply circuits, Arduino/Raspberry Pi projects, and protecting sensitive electronics from overvoltage. Comes in a standard TO-220 package for easy mounting and heat sinking.
