L4931CDT33 General Description

The L4931CDT33 is a reliable low-drop fixed voltage regulator designed and manufactured by STMicroelectronics. With a fixed output voltage of 3.3V and a maximum output current of 250mA, this device is suitable for a wide range of applications. Its wide input voltage range of 4.2V to 20V and low dropout voltage of 400mV at full load make it versatile and efficient

Application

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.
