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