DESCRIPTION

The LM2931 series 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

configation (SO-8), fully compatible to the older

L78L0 0 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

board in stand-by decreasing the total power

consumption. Ideal for automotive application

the LM2931 is proteceted from reverse battery

installations or 2 battery jumps. During the

transient, suchs as a a load dump (60V) when

the input voltage can exceed the specified

maximum operating input voltage (26V), the

regulator will automatically shut down to protect

both internal circuit and the load.
