SERIES

2% NEGATIVE VOLTAGE REGULATORS

s OUTPUT CURRENT TO 1.5A

s OUTPUT VOLTAGES OF -5; -6; -8; -12; -15;

-18; -20; -24V

s THERMAL OVERLOAD PROTECTION

s SHORT CIRCUIT PROTECTION

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.
