board in stand-by decreasing the total power  
consumption. Ideal for automotive application the  
LM2931xx is protected from reverse battery  
installations or 2 battery jumps. During the  
transient, such as a a load dump (60 V) when the  
input voltage can exceed the specified maximum  
operating input voltage (26 V), the regulator will  
automatically shut down to protect both internal  
circuit and the load.  
Description  
The LM2931xx are very low drop regulators. The  
very low drop voltage and the low quiescent  
current make them particular suitable for low  
noise, low power applications and in battery  
powered systems. In the 8 pin configuration (SO-  
8), fully compatible to the older L78Lxx family, a  
shut down logic control function is available.  
This means that when the device is used as a  
local regulator is possible to put a part of the  
Table 1.
