LM2931 IC LDO Regulator DIP-4 LM2931

Product Overview

The LM2931-N is a positive voltage regulator designed for applications requiring very low quiescent current and protection against harsh electrical environments. It features a quiescent current of 1 mA or less when supplying 10 mA loads, making it ideal for standby power systems, memory standby circuits, and low-power processor supplies. Originally designed for automotive use, the device includes robust protection against reverse battery installations, load dumps (up to 60 V), and reverse transients.
