Description
220uF x 2
Voltage regulating capacitors
To reduce power fluctuations of the
module in operation, use low-ESR
capacitors.
For LDO or DC/DC power supply, the
capacitance should be no less than
440uF. For battery power supply, the
capacitance can
be reduced to 100 uF to 200uF.

Table 3-3 Filter capacitor design for power supply
A stable power supply ensures the normal operation of AIW-356 DQ-N01 module. Make sure
that the ripple of the power supply less than 300mV in design. Ensure the power source
voltage should be not lower than 3.135V when in MAX consumption mode, otherwise the
module may shut down or restart. The power supply requirement is shown in the following
