COMMENT

VBAT

1,2

I

Module main power supply. The powersupply of module has to be a single voltage source of VBAT = 3.3V~4.6V,it must be able to provide sufficient current in a transmitting burst which typically rises to 2A

Vmax = 4.6V

Vmin = 3.3V

Vnormal = 4.0V

Recommend to used MIC29302/SP29302 High-Current Low-Dropout Regulators

VOUT

O

Supply 3.3V voltage for external circuit

Vmax = 3.4V

Vmin = 3.2V

Vnormal = 3.3V

Imax = 100mA

1. If unused, keep this pin open.

2. Recommend to added a 2.2~10uF bypass capacitor when using this pin to power supply.

GND
