Application Information
For the variable regulator IFX27001TFV, a minimum load current of 5 mA is necessary in order to keep the output
voltage regulated. If the application does not assure this minimum load requirement, the output voltage divider
should be dimensioned sufficiently

Output
The output current limitation is reduced as a function of the input voltage for high input voltages above 25 V.
The IFX27001 requires a 10 µF output capacitor with 0.1 Ω ≤ ESR ≤ 10 Ω for the stability of the regulation loop.
At the input of the regulator a capacitor is necessary for compensation of line influences. A series diode should be
used to eliminate negative voltages from the input. As a minimum, a 100 nF ceramic input capacitor should be
used. If the regulator is used in an environment with long input lines, an input capacitance of 10 µF is
recommended.
