LM2931, NCV2931 Series  
100 mA, Adjustable Output,  
LDO Voltage Regulator with  
60 V Load Dump Protection  
The LM2931 series consists of positive fixed and adjustable output  
voltage regulators that are specifically designed to maintain proper  
regulation with an extremely low inputtooutput voltage differential.  
These devices are capable of supplying output currents in excess of  
100 mA and feature a low bias current of 0.4 mA at 10 mA output.  
Designed primarily to survive in the harsh automotive environment,  
these devices will protect all external load circuitry from input fault  
conditions caused by reverse battery connection, two battery jump  
starts, and excessive line transients during load dump. This series also  
includes internal current limiting, thermal shutdown, and additionally,  
is able to withstand temporary powerup with mirrorimage insertion.  
Due to the low dropout voltage and bias current specifications, the  
LM2931 series is ideally suited for battery powered industrial and  
consumer equipment where an extension of useful battery life is  
desirable. The ‘C’ suffix adjustable output regulators feature an output  
inhibit pin which is extremely useful in microprocessorbased systems.
