Hi,
I need to design a DC to DC convertor from 9vDC to 5vdc and 3.3vDC.
Because the micro-controller which i am using requires 3.3v MAX.
But i am using some active sensors which requires more then 3.5v DC .
So i planed to design a DC to DC converter with 9vDC.
I goggled and found that LM7805 can be used for convert the 9v to 5v.
Is there any IC would take 9v as input and produce both 3.3v and 5v both.
after goggled i found some circuits and figured as attached.
whether ihe IC which indicated in the figure are ok.
I could not understand upto what extend they could give the Current whether in A or in mA
Battery:
Can i use a single 9v battery or 6AA battery's in series.
please tell me which would give more battery backup , because i am going to use this in WIRELESS SENSOR NETWORKS design .
thanking you
