- Mon Jun 20, 2016 1:36 pm #49494 Hi i saw the video of Kevin Darrah about Power Supply Considerations(https://youtu.be/sefQcqrbDik),
My project will work on 5v input (due to sensors i am using )
So as i understand from him the perfect LDO for me will be the TC1262-3.3VAB(max 6v) ,

1. Before I buy it i would like to hear what you are using and if their is more lower current drawing LDO then the TC1262 that you can advice ?

2. Also as i can see in the shop their is TC1262 with VAB And VDBTR names,
Whats this letters stands for and whats the different between them ?

3. Why he is connecting 10uF electrolytic capacitor parallel to 0.1uF Ceramic capacitor ? ( i know that its for filtering the esp8266 picks but why 2 and parallel ?)

Thanks you very much !

XC6203
HT7333
SPX3819

For the 2 capacitors in parallel, the small one is to filter noise, and the bigger one is to provide power reserve when spikes occurs, for this last one, even values of 47uF or 100uF can help.
