It is strongly recommended that the blocking capacitors at V
possible to the power supply and GND pins.
Recommended value for capacitors at V
Electrolythic capacitor C > 22 µF in parallel with a ceramic capacitor C = 100 nF. Value for elec-
trolytic capacitor depends on external loads, conducted interferences and reverse conducting
current I
Recommended value for capacitors at V
Electrolythic capacitor C > 10 µF in parallel with a ceramic capacitor C = 100 nF.
To reduce thermal resistance it is recommended that cooling areas be placed on the PCB as
close as possible to GND pins.
