Description

PAK

TAB

TO-220FP

The L79 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 L78 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.

TO-220
