DESCRIPTION

The L7900AC series of three-terminal negative

regulators is available in TO-220 and D

2PAK

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. 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.
