L7812ABD2T-TR

L7812ABD2T-TR is an L78 series positive voltage regulator IC. 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, these devices can be used with external components to obtain adjustable voltage and currents.
