Voltage Regulator, +12V, 7812, TO220-3 - 

L7812CV is a L78 series three-terminal positive regulator in TO-220 package and fixed 12V output voltage, making it useful in a wide range of applications. This regulator can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shut-down and safe 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, this device can be used with external components to obtain adjustable voltage and currents.
