LM309K  
Voltage Regulators  
GENERAL DESCRIPTION  
The LM309K is complete 5V regulator fabricated on a single silicon chip.  
The available output current is greater than 1A.  
He is designed for local regulation on digital logic cards, eliminating the distribution problems  
associated with single-point regulation. The devices are available in the TO3 power package.  
The regulators are essentially blow-out proof. Current limiting is included to limit the peak output  
current to a safe value. In addition, thermal shutdown is provided to keep the IC from overheating. If  
internal dissipation becomes too great, the regulator will shut down to prevent excessive heating.  
Considerable effort was expended to make these devices easy to use and minimize the number of  
external components. It is not necessary to bypass the output, although this does improve transient  
response somewhat. Input bypassing is needed, however, if the regulator is located very far from the  
filter capacitor of the power supply. Stability is also achieved by methods that provide very good  
rejection of load or line transients as are usually seen with TTL logic.  
Compliance to RoHS.

resistance can only approach the values specified, depending on the efficiency of the sink.
