TUTORIAL - 3.3 Voltage regulator AMS1117 3.3

Canal en Español: / electronoobs en español
Easy tutorial of how to build a nice 3.3V voltage regulator. The finished module will give you a nice and stable 3.3V output that you can use in your project. 3.3V output is often used in RC or IMU modules and most microcontrollers dosen't have a 3.3V output or if they do the output current is limited.

Is it necessary to use capacitors at input and output side?

[@priyadharshanakumara]

This help to control nrf power very easy and cheap ❤🎉

[@BADALICE]

Cool. This video is rocking; nice work area. It looks a lot like my set up. If I need a part, I always have one. Video cards I don't like to rob parts from. In fact, the less you mess with them the better, it sucks when you need to repair one. I love to rob TVs. stereos, vcrs, dvd players; oh and PCs for sure. Old Motherboards have lots of treasures, yep fun stuff. Looking up parts and finding out what kind of circuits they go in is just amazingly fascinating. I can tell you feel the same. Very, cool, dude.

[@danicho4053]

I'm new in your channel, dude you're amazing, your videos are so helpful and informative, thank you so much.

[@kosa2004]

This video helped me a lot :) Thanks!! Merry Xmas! 🎄🎄

[@vamshisaikrishnaarelli9778]

I'm from 2019, 3yrs after this video being uploaded☺️✌🏻

[@MinecraftHrvatska]

you helped me find that chip, thanks!

[@indiancitizen3408]

what if iddindt use any capcitors directly given 4.2 supply in vin and take 3.3 output

[@jeremytiempo9639]

Is it ok to supply it from 5v 1A mobile charger?

[@IHPU0]

i will test this now, but with ceramic smd capacitors. i keep you in touch, i have also burnt 3 ams1117 3.3v bi wrongly connecting (i follow the original ams datasheet), i want to test this. see you soon

[@IHPU0]

Another question, with my ohmmeter, the pin 2 (center) seems to be connected to the top pad, what is the pin connected to the top pad? you can also solder your ams1117 little below, to solder the top pad to a large copper plane for better heat dissipation.

[@IHPU0]

+IHPU0 Your website is cool, but there is a arborescence problem, when i click to acess the 3.3v regulator tutorial, i get a arduino radio communication tutorial (Really usefull tutorial for me thx). Dont forget to solve this issue bye

[@IHPU0]

thank you my friend it worked, i subscribed to you bye

[@Andreytxus]

Thanks a lot! I'm glad that it helped you. I will now change that. Must be a PHP problem! Thanks again and keep up

[@IHPU0]

***** I didnt know what i did, i checked the datasheet and its correct. I dont know why i used the pin 1 as output, pin 2 as ground and pin 3 as vin... I also making tutorials, i actually working on my Custom Gamecube regulator, the ams1117 is perfect for the 3.3v line that take at max 0.8Amps. bye

[@ricardogarcia7928]

C=0.1uF pin: 1 and 3 (input and gnd)....

[@ELECTRONOOBS]

my bad...pin 1 and 3 you are right! I'll place a note right now!!! thanks a lot

[@radius.indrawan]

ELECTRONOOBS 10 months passed and i don't see any note about it. many viewers could damage their chip by that mistake.

[@alham__aa]

can't we only use regulator without capacitors?

[@christinoccs]

Very good your channel and knowledges, thank for sharing but I have little time for youtube and I download all what I can but unfortunately I cant download this one

[@NathanCroucher]

How much can the input voltage change from 5v? Will that affect the 3.3v output?

[@jenntek.101]

it should be stable at 3.3v Max output current is 1.4a Max input voltage is 30v; but, make sure you use at least a 50v capacitor. Capacitors matter.

[@clementchu6459]

Cool video. i am new to electronic , and your video helps a lot. please keep on making it. love it. Also can you please explain what the capacitor for? thx.

[@habibihzaalamsyah1725]

Can i use this for arduino 5v to the nrf24l01? is it work prefectly? Thanks

[@SayWhaaaaaaaaaaaaaaaaaaaaaaat]

Why there is needed capacitors? can i use just the AMS1117? direct give 5v and get 3.3?

[@ELECTRONOOBS]

+Tomas Av. of course you can but BE CAREFOUL! The job of those capacitors is to fine regulate your voltage. If you have a small vlotage peak the capacitors will filter it. So I recomand you to always put those capacitors. The 0.1uF capacitor is for small fast voltage peaks. The bigger capacitors store a small charge in case your device needs more for a small amout of time. Is the basic configuration of a voltage regulator. Those are called coupling capacitors. Tanks and keep Up.

[@InGodWe-Trust]

+ELECTRONOOBS I just saw a design that uses 470uF on the output for AMS1117. It is connected to an ESP8266 and multilex 8 analog sensors. Is 470uF overkill or would 100 be okay?

[@shutdahellup69420]

Alesandro de Lima the value would increase as the current draw increase this nrf chip uses about 200mA so 100uf is ok...its ok to use bigger value but not ok to use too less value than recommended :)

[@GTX4747]

gave you a "like" for a cool vid, but there's something bothering me, as you mentioned, the arduino does have a 3.3v output pin, but you say it is "limited", what do you mean by that, why is limited about it and why you're circuit is not limited?

[@ELECTRONOOBS]

hi there. as I say in the vide the arduino 3.3 output is CURENT limited. The maximum current is around 200mA which is enough to light a led but it is not for the radio module. You will need an external voltage regulator which can give you a higher CURENT because the nrf24 module uses a lot. I recomand the ams1117 voltage regulator to 3.3 volts. keep up. thanks

[@iamboshon]

same question. can we use just ams1117 without capacitor and get 3,3v.?

[@ELECTRONOOBS]

+Dastan Rakhatov of course you can but BE CAREFOUL! The job of those capacitors is to fine regulate your voltage. If you have a small vlotage peak the capacitors will filter it.

[@mohammedal-alaw6249]

NO

[@mohammedal-alaw6249]

their existence is only for grantee! there is no ripple

[@dennzii]

I have a problem my ams1117 gives 3.8 volt output

[@princenp21]

Could i use 1000microFarad capacitor in across output voltage

[@lapidations]

Great vídeo! It would be perfect if your camera had autofocus.

[@touqeerahmed1438]

If 12v input through ams1117 so can we have 3.3v output please replay fast

[@yonnou7846]

thanks for the video.....

[@jjcampis]

Hi, can be used to power an esp01-s?

[@Vegetakhan]

Very odd I gave 5v in input and it's still giving 5v in output. Does anyone know what's wrong!?

[@amitghosh6966]

How much current can it handle ?

[@deeseal9269]

Tnx..u r my ticher....tnx alot..😗😗

[@mohammedal-alaw6249]

please check the data sheets if you connect directly it would never give you 3.3 volts return to the datasheets page @the beginning it needs resistors

[@mohammedal-alaw6249]

so I had to report you

[@mohammedal-alaw6249]

Actually I regret my actions because there are several models the ASM1117-3.3 would give you this directly but you would need Capacitors!

[@mohammedal-alaw6249]

I am truly sorry I regret this action :-(

[@codecage9333]

Nail clippers to cut wires! Get some proper tools! At least you didn't use a burning stick as a soldering 'iron.' I'll still give you a thumbs up!

[@manohar3787]

What's with the lighting man , too much shadow. You used to have a better setup . Thanks for the info

[@andreiboyka5787]

nice

[@massimilianogilli1164]

Why those capacitors values?

[@ELECTRONOOBS]

Big capacitor supply slow peaks of voltage and create a very stable regulated voltage. Small capaictors eliminate small current peaks.

[@massimilianogilli1164]

I know what there are needed for, i was just wondering if you have a rule of thumb for the values or if they are written in the datasheets

[@ELECTRONOOBS]

Yes, usually the datasheet gives you the comune values!

WHY must these people speak with such fake accents. Uber annoying.
