Hello,

I build guitar effects using the FV1. Basically all guitar effects are powered with +9V, so I need to get that down to +3.3v.

I've used the LM1117 and the 78L33 in FV1-based designs to power the chip. Both have worked fine so far, so I now mainly use the 78L33 as it's cheaper.

Is there any consensus as to regulator best suited to the specific needs of the FV1? I know that the dev board uses a SMD LM1117.

Regards,
David

I tend to use the T092 package 78l33 quite a lot but I also use the MC33269D3.3 in some designs if I need more mA from a small package as it can deliver 800mA if needed for other 3.3v circuitry.

The T092 package 78l33 has served me well, thank you for the reply!
