FEATURES  
DESCRIPTION  
The LM2931-N positive voltage regulator features a  
very low quiescent current of 1mA or less when  
supplying 10mA loads. This unique characteristic and  
the extremely low input-output differential required for  
proper regulation (0.2V for output currents of 10mA)  
make the LM2931-N the ideal regulator for standby  
power systems. Applications include memory standby  
circuits, CMOS and other low power processor power  
supplies as well as systems demanding as much as  
100mA of output current.

Very Low Quiescent Current  
Output Current in Excess of 100 mA  
Input-output Differential Less than 0.6V  
Reverse Battery Protection  
60V Load Dump Protection  
−50V Reverse Transient Protection  
Short Circuit Protection  
Internal Thermal Overload Protection  
Mirror-image Insertion Protection  
Designed originally for automotive applications, the  
LM2931-N and all regulated circuitry are protected  
from reverse battery installations or 2 battery jumps.  
During line transients, such as a load dump (60V)  
when the input voltage to the regulator can  
momentarily exceed the specified maximum  
operating voltage, the regulator will automatically shut  
down to protect both internal circuits and the load.  
The LM2931-N cannot be harmed by temporary  
mirror-image insertion. Familiar regulator features  
such as short circuit and thermal overload protection  
are also provided.  
Available in TO-220, TO-92, TO-263, or SOIC-8  
Packages  
•
Available as Adjustable with TTL Compatible  
Switch  
The LM2931-N family includes a fixed 5V output  
(±3.8% tolerance for A grade) or an adjustable output  
with ON/OFF pin. Both versions are available in a  
TO-220 power package, DDPAK/TO-263 surface  
mount package, and an 8-lead SOIC package. The  
fixed output version is also available in the TO-92  
plastic package.
