Smart Machine Smart Decision 3 Interface Application 3.1 Power Supply Pin 55, pin 56 and pin 57 are VBAT power input. On VBAT pads, when module works on CAT-M1 or NB-IoT mode, the ripple current is up to 0.6A typically. For steady voltage, the power supply capability must be up to 0.6A. On VBAT pads, when module works on EDGE or GPRS mode, The ripple current is up to 2A typically. For steady voltage, the power supply capability must be up to 2A.

If the voltage drop is below the minimum drop voltage, the module may shut down due to low voltage.
Smart Machine Smart Decision 3.1.2 Recommended Power Supply Circuit If the supply voltage exceeds the supply range of VBAT, the buck circuit should be used to meet the demand of power supply. When choosing buck chip, besides considering the maximum current output capability of IC to meet the demand of SIM7070 Series, it is also necessary to consider the low static power consumption of IC in PSM mode. Figure 7:Power supply reference circuit 3.1.
