packages and several fixed output voltages.
These regulators can provide local on-card
regulation, eliminating the distribution problems
associated with single point regulation;
furthermore, having the same voltage option as
the L78xxA positive standard series, they are
particularly suited for split power supplies. If
adequate heat sinking is provided, they can
deliver over 1.5 A output current.
Although designed primarily as fixed voltage
regulators, these devices can be used with
external components to obtain adjustable
voltages and currents.
