Description
The L78MxxAB series of three-terminal positive regulators is available in TO-220 and DPAK
packages and with 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 0.5 A output current. Although designed primarily as fixed
voltage regulators, these devices can be usedwith external components to obtain adjustable
voltage and currents.
