Hi,
I am using single Li ion battery to provide power to GSM Module, micro-controller and accelerometer. When GSM module transmits data, voltage for micro-controller drops and it gives wrong accelerometer values ( analog pins). Usually, Lithium ion Battery gives 4 Volts and I am unable to use linear regulator for fixed 3.3V output ( difference between output and input voltage is very less). One option that I have is to use Zener Diode. Any other option or suggestion would be highly appreciated. Thanks in advance.
