Description The IFX20001 is a monolithic integrated low-drop voltage regulator in the very small SMD package PG-SCT5955. It is designed to supply various loads (e.g. microprocessor) under over severe conditions. Therefore the device is equipped with additional protection functions against overload, short circuit and reverse polarity. In case of an overtemperature condition the regulator is automatically turned off by the integrated thermal protection circuit. Input voltages up to 45 V are regulated to VQ,nom = 3.3 V (V33 version) or 5.0 V (V50 version). The output is able to drive a load of 30 mA while it regulates the output voltage within a 4% accuracy. To save energy the device can be switched in stand-by mode via an inhibit input which causes the current consumption to drop below 5 μA.

The regulation loop controls the output to achieve a stabilized output voltage. Figure 3 shows a typical application circuit. In order to maintain the stability of the control loop the IFX20001 output requires an output capacitor CQ of at least 3.3 μF with a maximum permissible ESR of 2 Ω. It is recommended to use a multi layer ceramic capacitor for CQ. If aluminum electrolytic and tantalum capacitors are selected as output capacitors they must be carefully chosen to cover the required ESR range over the full operating temperature range of -40 °C to 125 °C. At the input of the regulator a capacitor is required for compensating line influences. A resistor of approximately. 1 Ω in series with the input capacitor (CI) can dampen oscillations that could occur due to the input line inductance and the input capacitor. If the regulator is sourced via long input lines of several meters it is recommended to place an additional capacitor ≥ 47 μF at the input.
