IC L7800
The L7800 series of three-terminal positive regulators is available in TO-220 TO-220FP TO-3 and D2PAK 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 employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible.
Circuit Regulator L7800
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 voltages and currents.
