LM2931 Overview
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- (SO-8), fully patible with the older L78L family, a shutdown logic control function is available.
