■ SHORTCIRCUIT PROTECTION
■ OUTPUT TRANSITIONSOAPROTECTION
DESCRIPTION
The L7800 series of three-terminal positive regulators is available in TO-220 ISOWATT220 TO-3 and D
2
PAK packages and several fixed output voltages, making it useful in a wide range of applications.Theseregulators 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 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustablevoltages and currents.
