DESCRIPTION
The L7900AC series of three-terminal negative
regulators is available in TO-220 and D²PAK
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 L7800A positive standard series, they are
particularly suited for split power supplies. If
adequate heat sinking is provided, they can
deliver over 1.5A output current.
Although designed primarily as fixed voltage
regulators, these devices can be used with
external components to obtain adjustable voltages
and currents.
