4 Electric Feature and Reliability
This chapter describes the electric features and reliability of N75-A, including current and voltage of
each power pin, operating and storage temperature ranges, and ESD protection features.

If the voltage is lower than threshold, the module might fail to start. If the voltage is higher than
threshold or there is a voltage burst during the startup, the module might be damaged permanently.
If you use LDO or DC-DC to supply power for the module, ensure that it outputs at least 2 A current.
When the module works at maximum power in GSM mode, the peak current might reach 2A. Add a
large capacitor to the VBAT pin to enhance the capability to output continuous current and avoid
voltage drop.

If the module works in an environment of -35°C to -40°C or 75°C to 85°C, RF performance might be
worse. This does not affect the running of the module. The RF performance will meet the 3GPP standard
after the temperature reaches the operating range.
