Product Summary

The 7805 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 7805 can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. The 7805 employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, the 7805 can deliver over 1A output current. Although designed primarily as fixed voltage regulators, the 7805 can be used with external components to obtain adjustable voltage and currents.
