The circuit below supplies 3.3V to an antenna (3.3VGreen), which then gives GNSS info to a control module (ANT_GNSS). The attached antenna is datasheet and only consumes about 10mA
But I am wondering what resistor value I need at the BJT's base to bring the transistor to saturation? The transistor's datasheet is linked here datasheet. I am thinking that if h_fe is 100 @10mA (collector current) then base current needs to be at least 10mA/100 or 0.1mA to drive to saturation? Following this BJT Tutorial, but I have no practical experience.
