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.

Absolute maximum ratings

Note: Absolute maximum ratings are those values beyond which damage to the device may occur. Functional operation under these condition is not implied.
