LM109/LM309  
5-Volt Regulator  
does improve transient response somewhat. Input bypass-  
ing 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.  
General Description  
The LM109 series are complete 5V regulators fabricated on  
a single silicon chip. They are designed for local regulation  
on digital logic cards, eliminating the distribution problems  
association with single-point regulation. The devices are  
available in two standard transistor packages. In the  
solid-kovar TO-5 header, it can deliver output currents in ex-  
cess of 200 mA, if adequate heat sinking is provided. With  
the TO-3 power package, the available output current is  
greater than 1A.  
Although designed primarily as a fixed-voltage regulator, the  
output of the LM109 series can be set to voltages above 5V,  
as shown. It is also possible to use the circuits as the control  
element in precision regulators, taking advantage of the  
good current-handling capability and the thermal overload  
protection.  
The regulators are essentially blowout 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.  
Features  
n Specified to be compatible, worst case, with TTL and  
DTL  
n Output current in excess of 1A  
n Internal thermal overload protection  
n No external components required  
Considerable effort was expended to make these devices  
easy to use and to minimize the number of external compo-  
nents. It is not necessary to bypass the output, although this
