Description
Maturity status link
LM2931
The LM2931 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
with the older L78L family, a shutdown logic control function is available. This means
that when the device is used as a local regulator it is possible to put a part of the
board in standby, decreasing total power consumption. Ideal for automotive
applications, LM2931 is protected from reverse battery installations or 2 battery
jumps. During the transient, such as a 60 V load dump, when the input voltage can
exceed the specified maximum operating input voltage of 26 V, the regulator
automatically shuts down to protect both internal circuitry and the load.
