Line Regulation of 0.04%/V

Output Voltage Tolerances of  
profile metal three lead TO (NDT) and the LM340LA  
are also available in the plastic TO-92 (LP). With  
adequate heat sinking 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 provided 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.

DESCRIPTION  
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 output voltage  
tolerance (specified over the full military temperature  
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 combination 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  
distribution 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 electronic equipment. Although  
designed primarily as fixed voltage regulators, these  
devices can be used with external components to  
obtain adjustable voltages and currents.
