Description

The L79xxC series of three-terminal negative

regulators is available in TO-220, TO-220FP and

D²PAK 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;

furthermore, having the same voltage option as

the L78xx 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.
