Description

The L78xx series of three-terminal positive regulators is available in TO-220, TO-220FP , TO-3, D 2PAK 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 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 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents. TO-220FP TO-3 TO-220 D²PAKDPAK Table 1.
