Description
The IFX20002 is a monolithic integrated low drop voltage regulator in a very small SMD package PG-SCT595-5.
It is designed to supply e.g. micro controller, sensors, etc or may serve as standby supply under severe conditions.
Therefore the device is equipped with additional protection functions against overload, short circuit and reverse
polarity. At over temperature the regulator is automatically turned off by the integrated thermal protection circuit.
Input voltages up to 40 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.

Application Diagram
The output voltage of the IFX20002 is divided and compared to an internal reference of 2.5 V typical. A 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 IFX20002
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, e.g. the TDK C3216X7R1C475M with a nominal
capacitance of 4.7 μF. Aluminum electrolytic as well as tantalum capacitors do not cover the required ESR range
over the full operating temperature range of Tj = -40 °C to +125 °C.
At the input of the regulator an input capacitor is necessary for compensating line influences (100 nF ceramic
capacitor recommended). A resistor of approx. 1 Ω in series with CI can dampen oscillations that could occur due
to the input inductivity and the input capacitor. If the regulator is sourced via long input lines of several meters it is
recommended to place an additional electrolytic capacitor ≥ 47 μF at the input.
