L79xxAC

2 % negative voltage regulators

Features

■ Output current to 1.5 A

■ Output voltages of -5; -12; -15 V

■ Thermal overload protection

■ Short circuit protection

■ Output transition SOA protection

Description

The L79xxAC 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 L78xxA 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.
