STMicroelectronics L4931 Manuals

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 is a type of very low dropout voltage regulator with features such as very low dropout voltage, quiescent current, and output current up to 250mA. It is suitable for low noise, low power, and battery-powered systems.

The L4931 series are very Low Drop regulators available in TO-220, SO-8, DPAK, PPAK and TO-92 packages and in a wide range of output voltages. The very Low Drop voltage (0.4V) and the very low quiescent current make them particularly suitable for Low Noise, Low Power applications and specially in battery powered systems. In PPAK and SO-8 packages a Shutdown Logic Control function is available TTL compatible. 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 the total power consumption. It requires only a 2.2 µF capacitor for stability allowing space and cost saving.

L4931 series is a very low dropout regulator with extremely low dropout voltage (0.4V) and extremely low quiescent current (typical 50µA), particularly suitable for low noise, low power applications, especially in battery powered systems.
