MC78XX/LM78XX/MC78XXA  
3-Terminal 1A Positive Voltage Regulator  
Features  
Description  
• Output Current up to 1A  
• Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V  
• Thermal Overload Protection  
The MC78XX/LM78XX/MC78XXA series of three  
terminal positive regulators are available in the  
TO-220/D-PAK package and with several fixed output  
voltages, making them useful in a wide range of  
• Short Circuit Protection  
• Output Transistor Safe Operating Area Protection  
applications. Each type employs internal current limiting,  
thermal shut down and safe operating area protection,  
making it essentially indestructible. If adequate heat sinking  
is provided, they can deliver over 1A output current.  
Although designed primarily as fixed voltage regulators,  
these devices can be used with external components to  
obtain adjustable voltages and currents.
