For automotive applications please refer to the Infineon TLx (TLE, TLS, TLF...) voltage regulator products. Description The IFX30081SJV 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 current consumption of only 5 µA this regulator is perfectly suitable for battery operated systems as well as supplies for sensors. The IFX30081SJV is available with an adjustable output voltage with an accuracy of 2 % and maximum output current up to 50 mA. The regulation concept implemented in the IFX30081SJV 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 Type IFX30081SJV Data Sheet Package PG-DSO-8 2 Marking 30081SJV Rev. 1.0, 2015-02-04 IFX30081SJV Overview limitation and overtemperature 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. Choosing External Components An input capacitor CIN is recommended to compensate line influences. The output capacitor COUT is necessary for the stability of the regulating circuit. Stability is guaranteed at values COUT ≥ 1µF and an ESR ≤ 100 Ω within the whole operating range.
