All the AM2LW-Z Series have been tested with the above recommended test circuit.
This series should be tested under load.
If it is necessary to further decrease the input/output ripple, the value of the filter capacitor can be increased; a capacitor with a low ESR
should be used. Excessive filter capacitance can cause start up problems with the converter.
In general, the recommended capacitance values are:
Cin: 10μF~47μF
Cout: 10μF/100mA
