The KA79XX / KA79XXA / LM79XX series of three-terminal negative regulators are available in a TO-220 package with several fixed output voltages, making them
useful in a wide range of applications. Each type employs internal current limiting, thermal shutdown, and safe operating area protection.
• Output Current in Excess of 1 A • Output Voltages of: -5 V • Internal Thermal Overload Protection • Short-Circuit Protection • Output Transistor Safe Operating Area Compensation
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.
