L7812CV Voltage Regulator 1A 12V 3-Pin TO-220 (Pk of 2)

Manufactured by ST Microlectronics - TO-220 package

3 terminal 12V 1A fixed voltage regulator.

These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
