7812A is one of the linear regulator ICs (integrated circuits) that output accurate constant voltage. This IC can output a constant voltage of 12V even if the input voltage is not stable. The 7812A is used in electronic circuits requiring a constant voltage of 12V to minimize the effects from input voltage fluctuations.

The 7812A is housed in a TO-220 package, allowing external components such as cooling fins to dissipate heat. This IC is used in a wide range of applications such as audio equipment, power supply units, instrumentation, and automotive electronics.

Note that the 7812A is a type of common constant voltage regulator IC, and other voltage versions (eg, 7805A, 7809A, etc.) also exist. In addition to linear type constant voltage regulator ICs, there are also switching types, which are used to design high-efficiency power supply circuits.
