Description as follow:

The L7812CV is a three-terminal positive regulator. It is available in TO-220, TO-220FP, TO-220FM, TO-3 and D2PAK packages and several fixed output voltages, making it useful in a wide range of applications. The L7812CV can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. The L7812CV employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, the L7812CV can deliver over 1A output current. Although designed primarily as fixed voltage regulators, the L7812CV can be used with external components to obtain adjustable voltage and currents.
