Y'know a lot of you have taken issue with the regulator being right next/touching the capacitor... I've had zero issues with this. Sure if you are trying to drop from 12V to 3.3 this may be an issue but 90% of the time I just want to go from 5V (or even 4 on a LiPo) to 3.3. The heat generated at this voltage is minimal and does not seem to affect the cap in any way. Also side note - this is not meant as a regulator for a production product - this is a regulator for prototyping/medium term projects, so any issues that -could- arise from 50k hours of use is not exactly something that I would consider a problem for this build. If you came here looking for a long term/production ready regulator solution then take another look at the channel name... And with that, on with the show!

A while ago I showed all of you how to build a quick voltage regulator for the ESP8266 microcontroller that was based on the LM1117. Although that works well in general, I've been tipped off to a new regulator that is much smaller and has a low dropout voltage (9mV!). This new regulator design is based on the HT7333-A.
