Hello,
I'm using 3.3V dsPICs (and 3.3V bluetooth modules) on my current project, and normally I would just go with a cheap linear regulator. However battery pack is 12V and the 8.7V voltage drop across the regulator means alot of lost energy (and heat), so I'm looking into switching regulators/charge pumps.
I am wondering if anyone used stepdown charge pump regulators, and how good are they compared to linear regulators.
Thanks.
