Typical Application for L7809C High output current with short circuit protection

Typical Application for L7809C High output current with short circuit protection. The L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, D2PAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shutdown and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current
