5.5.2 Power Consumption

The power consumptions of MU709s-2 module in different scenarios are respectively
listed in Table 5-6 toTable 5-8 .
The power consumption listed in this section is tested when the power supply of the
MU709s-2 module is 3.3 V, and all of test values are measured at room temperature.

The VCC_3V3 minimum value must be guaranteed during the burst (with 2.7 A Peak in GSM 2
slot mode). So a low-dropout (LDO) regulator or switch power with current output of more than
3.5 A is strongly recommended for external power supply.
