MC79XX/MC79XXA/LM79XX  
3-Terminal 1A Negative Voltage Regulator  
Features  
Description  
• Output Current in Excess of 1A  
• Output Voltages of -5, -6, -8 , -9, -10, -12, -15, -18 and -  
24V  
• Internal Thermal Overload Protection  
• Short Circuit Protection  
The MC79XX / MC79XXA/ LM79XX 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 shut down and  
safe operating area protection, making it essentially  
indestructible.  
• Output Transistor Safe Operating Area Compensation
