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.

Features

■ Output current up to 1.5 A

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

■ Thermal overload protection

■ Short circuit protection

■ Output transition SOA protection
