If the voltage is lower than threshold, the module might fail to start. If the voltage is higher than
threshold or there is a voltage burst during the startup, the module might be damaged permanently.
⚫
If you use LDO or DC-DC to supply power for the module, ensure that it outputs at least 2 A
current.When the module works at maximum power in GSM mode, the peak current might reach 2A.
Add a large capacitor to the VBAT pin to enhance the capability to output continuous current and
avoid voltage drop.

, RF performance might be
worse. This does not affect the running of the module. The RF performance will meet the 3GPP standard
after the temperature reaches the operating range.
