KA78XXE/KA78XXAE  
3-Terminal 1A Positive Voltage Regulator  
Features  
Description  
Output Current up to 1A  
The KA78XXE/KA78XXAE series of three-terminal posi-  
tive regulator are available in the TO-220/D-PAK package  
and with several fixed output voltages, making them use-  
ful in a wide range of applications. Each type employs  
internal current limiting, thermal shut down and safe  
operating area protection, making it essentially inde-  
structible. If adequate heat sinking is provided, they can  
deliver over 1A output current. Although designed pri-  
marily as fixed voltage regulators, these devices can be  
used with external components to obtain adjustable volt-  
ages and currents.  
Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V  
Thermal Overload Protection  
Short Circuit Protection

Notes:  
1. To specify an output voltage. substitute voltage value for "XX." A common ground is required between the input and  
the Output voltage. The input voltage must remain typically 2.0V above the output voltage even during the low point  
on the input ripple voltage.  
2. C is required if regulator is located an appreciable distance from power Supply filter.
