I do not know how I get myself into these positions but here it is!

I am working on a Bluetooth sensor that must be powered from a 3.6V Lithium-Ion battery. Battery life can be a 4, 5 hours, I am going to add a charging circuit. The Bluetooth transceiver must run from max 3.4v to min 3.2v 120mA TX and 50mA receive. I have an AD595 that requires 5v. I am getting confused to which regulator, charge pump etc.. will do the job. I am looking at using an LTC1517-5 20mA for 5v to a PIC12F675 and the AD595.

Can anyone suggest a regulator or how I can ensure 3.3V to my Bluetooth circuit?

Thanks for the help,

Scott
