KA79XX / KA79XXA / LM79XX
3-Terminal 1 A Negative Voltage Regulator
September 2014
Features
• Output Current in Excess of 1 A
• Output Voltages of: -5 V, -6 V, -8 V, -9 V, -12 V, -15 V,
-18 V, -24 V
• Internal Thermal Overload Protection
• Short-Circuit Protection
• Output Transistor Safe Operating Area Compensation
Description
The KA79XX / KA79XXA / LM79XX series of three-termi-
nal negative regulators are available in a TO-220 pack-
age 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.
