G+_Rud Dog Posted September 18, 2017 Share Posted September 18, 2017 Suggestions for a small 12VDC in 3.3V out for current project? Looking at this one but can't help thinking wasted power in the form of heat? https://www.adafruit.com/product/2165 Link to comment Share on other sites More sharing options...

G+_Shooter_FPV (Shooter_FP Posted September 19, 2017 Share Posted September 19, 2017 Can't go wrong with Pololu... it's a long list but we don't know what your project is... pololu.com - Pololu - Step-Down Voltage Regulators Link to comment Share on other sites More sharing options...
G+_John Sullivan Posted September 19, 2017 Share Posted September 19, 2017 Going from 12 v to 3.3 v is going to generate waste in the form of heat, no matter which device you use. That 8.7 v has to go somewhere. How much heat depends also on how much current, so just make sure that your converter can supply the milliamps your project needs, and try not to fret overmuch on the energy that is wasted. However, if you find it keeping you up at night, consider using a supply that is closer to the 3.3v, instead of the 12 v one Link to comment Share on other sites More sharing options...
G+_Black Merc Posted September 19, 2017 Share Posted September 19, 2017 Yes, linear regulator will surely generate lots of heat, by the nature of the device. However, the buck regulators padre mentioned back around the quad episodes from rtf-quads should not generate heat in the same degree.(design is a switching type) Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted September 19, 2017 Author Share Posted September 19, 2017 Sorry about the limited information. The suggestions got the memory working, I have one of those buck regulators padre mentioned gonna have to dig it out of the parts bin. Thanks all.
