7812CT PDF Datasheet – 12V, Voltage Regulator – MC7812CT

This post explains for the Voltage Regulator. A voltage regulator is an electronic device that is used to maintain a constant voltage level, regardless of changes in load or input voltage.

It does this by adjusting the output voltage so that it remains within a specified range.

This helps to ensure that the voltage supplied to a device remains within the acceptable range, even under varying conditions such as changes in temperature or load.

The Part Number is 7812CT, MC7812CT.

The function of this semiconductor is 1A, 12V, Voltage Regulator.

The package is TO-220 Type

Manufacturer: Fairchild Semiconductor

The 7812CT, MC78XX / LM78XX / MC78XXA series of three terminal positive regulators are available in the TO-220/D-PAK package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
