The L4931 series is a very low dropout regulator with very low quiescent current and logic-controlled electronic shutdown function. It is suitable for low noise, low power, and battery-powered systems.
The L4931 series are very low dropout voltage regulators available in TO-220, SO-8, DPAK, PPAK, and TO-92 packages. They feature a very low dropout voltage of 0.4V and very low quiescent current, making them suitable for low noise, low power, and battery-powered applications. In PPAK and SO-8 packages, a shutdown logic control function is available that is TTL compatible.
