L79xxC

Negative voltage regulators

Features

■ Output current up to 1.5 A

■ Output voltages of -5; -8; -12; -15; -20 V

■ Thermal overload protection

■ Short circuit protection

■ Output transition SOA protection

Description

The L79XXC 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 L78XX 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.
