VAUX/PWRMON Power Output
A 1.8V regulated power supply output is provided in order to supply small devices from
the module. The signal is present on Pad 43
This output is always active as long as the module is powered (VBATT applied). It is also
active during module sleep mode/ PSM mode.
The operating range characteristics of the supply are:

1.80V
1.9V
Output current

50mA
Output bypass
capacitor
(inside the module)
100nF
NOTE:
The Output Current MUST never be exceeded; care must be taken
when designing the application section to avoid having an excessive
current consumption.
If the Current is exceeding the limits it could cause a Power Off of the
module.
Warning:
The current consumption from VAUX/PWRMON increases the
modem temperature.
