4. POWER SUPPLY
The power supply circuit and board layout are an important part of the product design.
Make sure to follow the guidelines and requirements for optimal performance .
Power Supply Requirements
The external power supply must be connected to VBATT and VBATT_PA pads and must
fulfil the following requirements:
Table 11: Power Supply Requirements
Warning: The range 2.6V - 3.2V can be used only if both USB and 2G
are disabled.
Warning: The modem supply voltage must never exceed the
Extended Operating Voltage Range.
Inaccurate implementation of power supply guidelines described in
this document can cause a faulty module.
Note: For PTCRB approval on the final products the power supply
must be within the “Operating Voltage Range”.
Note: The power supply section of the application must be carefully
designed to avoid excessive voltage drop during peak transmission
current absorptions. If the voltage drops beyond the limits of the
Extended Operating Voltage range, an unintentional module power
off can occur.
