DESCRIPTION

The L7900 series of three-terminal negative

regulators is available in TO-220, ISOWATT220

TO-3 and D

2PAK 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 L7800 positive standard series, they are

particularly suited for split power supplies. In

addition, the -5.2V is also available for ECL

system.

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.
