LM140L/LM340L Series  
3-Terminal Positive Regulators  
General Description  
vided to limit internal power dissipation. If internal power  
dissipation becomes too high for the heat sinking provided,  
the thermal shut-down circuit takes over, preventing the IC  
from overheating.  
The LM140L series of three terminal positive regulators is  
available with several fixed output voltages making them  
useful in a wide range of applications. The LM140LA is an  
improved version of the LM78LXX series with a tighter out-  
put voltage tolerance (specified over the full military tem-  
perature range), higher ripple rejection, better regulation and  
lower quiescent current. The LM140LA regulators have 2%  
VOUT specification, 0.04%/V line regulation, and 0.01%/mA  
load regulation. When used as a zener diode/resistor com-  
bination replacement, the LM140LA usually results in an  
effective output impedance improvement of two orders of  
magnitude, and lower quiescent current. These regulators  
can provide local on card regulation, eliminating the distribu-  
tion problems associated with single point regulation. The  
voltages available allow the LM140LA to be used in logic  
systems, instrumentation, Hi-Fi, and other solid state elec-  
tronic equipment. Although designed primarily as fixed volt-  
age regulators, these devices can be used with external  
components to obtain adjustable voltages and currents.  
For applications requiring other voltages, see LM117L Data  
Sheet.  
Features  
n Line regulation of 0.04%/V  
n Load regulation of 0.01%/mA  
n Output voltage tolerances of 2% at Tj = 25˚C and 4%  
over the temperature range (LM140LA) 3% over the  
temperature range (LM340LA)  
n Output current of 100 mA  
n Internal thermal overload protection  
n Output transistor safe area protection  
n Internal short circuit current limit  
n Available in metal TO-39 low profile package  
(LM140LA/LM340LA) and plastic TO-92 (LM340LA)  
The LM140LA/LM340LA are available in the low profile  
metal three lead TO-39 (H) and the LM340LA are also  
available in the plastic TO-92 (Z). With adequate heat sink-  
ing the regulator can deliver 100 mA output current. Current  
limiting is included to limit the peak output current to a safe  
value. Safe area protection for the output transistor is pro-
