Dc regulator for batterry device

Hi,

I am working on a WSN project  montoring CH4 gas. I used a LiFePO4 battery, voltage from 2.0 to 3.6v,i need a regulator to convert the voltage to a fixed 3.0v.and this 3.0v power supply will power a cc2530+cc2591 ,a INA :AD8236,a dual omp:AD4505-2,and a gas sensor. The total output current are less than 1A. So i want a low cost, low-power, high-efficent regulator.It does not matter  wether the output connect the input or  not. Does ADI have this kind regulator ,suit for my portable device?

  • The ADP1613 will probably be able to give 300-400mA, since you said <1A I was just guessing what that meant.

    Alternatively the ADP2304 could be used but in that case the operation will be limited at 2.2V. Can you really discharge at LI batery below that? 2.0V seems pretty low.
