Hello
I have a supply voltage of around 4.5V consisting of 3 AA batteries. I need this stepped down to 3.3V. My current requirement is around 150mA. So currently I am considering 2 options:-
1) Using a LDO IC to obtain 3.3v
2) Using a buck converter
I have uploaded my entire schematic above.
Some of my concerns are that
1) Will smps(inductor coil) interfere with my zigbee signals .
2) If i use a LDO will i need a heat sink assuming that my heat dissipated will be around 0.3W.
Also it would be of great help if someone could recommend some highly efficient ICs for LDO & BuckBoost , considering the fact that there are so many of them available online.
