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.

This fractional voltage is compared to an internal voltage reference and drives the pass transistor accordingly. The control loop stability depends on the output capacitor COUT, the load current, the chip temperature and the internal circuit design. To ensure stable operation, the output capacitor’s capacitance and its equivalent series resistor ESR requirements given in “Functional Range” on Page 8 have to be maintained. For further details please refer to the typical performance graph “Output Capacitor Series Resistor ESR(COUT) versus Output Current IOUT” on Page 13. Since the output capacitor is used to buffer load steps, it should be sized according to the application’s needs. An input capacitor CIN is not required for stability, but is recommended to compensate line fluctuations. An additional reverse polarity protection diode and a combination of several capacitors for filtering should be used. Connect the capacitors close to the regulator terminals. In order to prevent overshoots during start-up, a smooth ramping up function is implemented. This ensures almost no overshoots during start-up, mostly independent from load and output capacitance. Whenever the load current exceeds the specified limit, e.g. in case of a short circuit, the output current is limited and the output voltage decreases. The over temperature shutdown circuit prevents the IC from immediate destruction under fault conditions (e.g. output continuously short-circuit) by switching off the power stage. After the chip has cooled down, the regulator restarts. This oscillatory thermal behavior causes the junction temperature to exceed the 150° C maximum and significantly reducing the IC’s life.
