Description

The L79 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 L78 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
• Output tolerance 2% (AC version) or 4% (C version) at 25°C
