Description

The LM2931AD33 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 appl ications and in battery powered systems. In the 8 pin configation (SO-8), fully compatible to the older L78L00 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 LM2931AD33 is proteceted from reverse batteryinstallations or 2 bat tery 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.
