IFX8117 Application Hints 6 Application Hints 6.1 External Components Input Capacitor An input capacitor is recommended to compensate line influences. As a minimum a 100 nF ceramic input capacitor should be used to filter high frequency noise. For buffering line transients a capacitance of 10µF is suggested. Output Capacitor The output capacitor is part of the regulation loop of the regulator and therefore important to maintain stability.

IFX8117 Application Hints 6.2 Protection Diodes 1N4001 (optional ) IFX 8117 MEV VI VQ R1 ADJ R2 Protection_Diode.vsd Figure 7 IFX8117MEV with Protection Diode In normal operating conditions, no diodes are needed for protection of the device. In case the input is shorted to GND and the output capacitor is still charged, a peak current can flow from the output to the input of the regulator. This peak current depends on the size and the equivalent series resistor (ESR) of the output capacitor.
