3-TERMINAL POSITIVE VOLTAGE REGULATOR  
LM7805XE3  
Description  
The LM7805XE3 series of three-terminal positive regulators are  
available in the TO-220AB package. These regulators can provide  
local on -card regulation, eliminating the distribution problems  
associated with single point regulation. Each employs internal current  
TO-220AB  
limiting, thermal shutdown 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.  
LM7805XE3 is characterized for operation from 0°C to +125°C, and if operating temperature is  
always high, please refer to the power dissipation curve.
