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 configuration

(SO-8), fully compatible to the older L78L00

family, a shut down Logic Control function is

available.

in stand-by decreasing the total power

consumption. Ideal for automotive application the

LM2931 is protected from reverse battery

installations or 2 battery jumps. During the

transient, such 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.

This means that when the device is used as a

local regulator is possible to put a part of the board
