The IFX30081LDV33 is a wide input voltage, low drop out voltage and ultra low quiescent current linear voltage regulator. With a wide input voltage range of 2.75 V to 42 V and ultra low quiescent current of only 5.5 μA this regulator is perfectly suitable for battery operated systems as well as supplies for sensors. The IFX30081LDV33 is available in a fixed 3.3V output voltage with an accuracy of 2% and maximum output current up to 50 mA. The regulation concept implemented in the IFX30081LDV33 combines fast regulation and very good stability while requiring only a small ceramic capacitor of 1 μF at the output. Internal protection features like output current limitation and over temperature shutdown are implemented to protect the device against failures like output short circuit to GND, over-current and over-temperature. The device can be switched on and off by the enable feature. When the device is switched off, the current consumption is less than 1 μA.
