LM140/LM340A/LM340/LM7800C  
Series 3-Terminal Positive Regulators  
General Description  
Features  
n Complete specifications at 1A load  
The LM140/LM340A/LM340/LM7800C monolithic 3-terminal  
positive voltage regulators employ internal current-limiting,  
thermal shutdown and safe-area compensation, making  
them essentially indestructible. If adequate heat sinking is  
provided, they can deliver over 1.0A output current. They are  
intended as fixed voltage regulators in a wide range of appli-  
cations including local (on-card) regulation for elimination of  
noise and distribution problems associated with single-point  
regulation. In addition to use as fixed voltage regulators,  
these devices can be used with external components to ob-  
tain adjustable output voltages and currents.  
=

±
n Output voltage tolerances of 2% at Tj 25˚C and 4%  
over the temperature range (LM140A/LM340A)  
n Line regulation of 0.01% of VOUT/V of ∆VIN at 1A load  
(LM140A/LM340A)  
n Load regulation of 0.3% of VOUT/A (LM140A/LM340A)  
n Internal thermal overload protection  
n Internal short-circuit current limit  
n Output transistor safe area protection  
n P+ Product Enhancement tested  
Considerable effort was expended to make the entire series  
of regulators easy to use and minimize the number of exter-  
nal components. It is not necessary to bypass the output, al-  
though this does improve transient response. Input bypass-  
ing is needed only if the regulator is located far from the filter  
capacitor of the power supply.

steel TO-3 power package. The LM340A/LM340/LM7800C  
series is available in the TO-220 plastic power package, and  
the LM340-5.0 is available in the SOT-223 package, as well  
as the LM340-5.0 and LM340-12 in the surface-mount  
TO-263 package.
