DESCRIPTION

The

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.
