3-TERMINAL POSITIVE VOLTAGE REGULATOR  
Description  
TO-252  
The H7805_J series of three-terminal positive regulators are available  
in the TO-252 package. These regulators can provide local on-card  
regulation, eliminating the distribution problems associated with single point regulation. Each  
employs internal current limiting, thermal shut-down and safe operating area protection, making it  
essen-tially 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.  
H7805_J is characterized for operation from 0°C to +125°C, and if operating temperature is  
always high, please refer to the power dissipation curve.
