LPM2100 qg NB module hardware manual current peak will be generated, which leads to a larger ripple in the power supply. If the instantaneous voltage drop causes the VBAT power supply voltage to be too low or the power supply current is insufficient, the module may turn off or restart. Therefore, the module power supply needs to provide enough current to ensure the normal operation of the module. When the external power supply is connected to the module, the VBAT_BB and VBAT_RF need to use the star line.
