KA79XX/KA79XXA  
3-Terminal 1A Negative Voltage Regulator  
Features  
Description  
• Output Current in Excess of 1A  
The KA79XX/KA79XXA series of three-terminal negative  
regulators are available in TO-220 package and 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, making it essentially indestructible.  
• Output Voltages of -5, -6, -8, -9, -12, -15, -18 , -24V  
• Internal Thermal Overload Protection  
• Short Circuit Protection  
• Output Transistor Safe Operating Area Compensation
