5.6 Power Supply Features

5.6.1Input Power Supply

Table‎ 5-5lists the requirements for input power of the ME909 module.

Table 5-5Requirements for input power for the ME909 module

Parameter	Min.	Typ.	Max.	Ripple	Unit

VCC_3V3	3.0	3.3	3.6	0.05	V

Figure 5-1Power Supply During Burst Emission

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.
