Hello everyone, I am using Raspberry Pi Pico with Esp 01 here my model (ESP8266 ESP-01 Seri Wifi Kablosuz Verici Modülü ) but Raspberry Pi Pico's 3.3V don't have enough current so I decided to use LM1117 here ( LM1117 - LD1117 3V3 Ayarlı Regülatör 3.3V TO220 Uygun Fiyatıyla Satın Al - Direnc.net®). My connection is like this:
Pico's 5V to - LM's 1117 Vin.
Pico's GND to LM 1117 's GND.
ESP01's 3.3V and CH PD- to LM1117 's Vout.
Esp01's GND to LM1117's GND.
Esp01's RX TX to Raspberry Pi Pico's TX RX.
I am using 2 caps first one 10 µF Vin side and second one is 100 µF Vout side.
When I measure the current's (5V-200 mA in) and (3.3V-92mA out) I need at least 180mA to Esp01 work. How can I increase current.
So first of all the regulator is linear, that means nearly all current that is available to it, it can provide to a maximum of it's 800mA rating (though then you would need a heatsink) The regulator is not the issue.
You should swap those over.
You are measuring the current that is drawn. If the ESP needs more, it will draw more.
Add the RST pin to that 3.3v, most ESP-01's have a pullup resistor to RST, but not all of them do.
Where is that 5v coming from, VBUS ?
I'd say you have the power supply setup correctly (more or less) and your issue is caused by something else.
What is it you are trying to make the ESP-01 do ?
Hi,
A picture is worth a thousand words.
Can you please post a circuit diagram of your project.
Do you have a DMM?
Thanks.. Tom.... 
You should swap those over.
I swap them It didn't change
You are measuring the current that is drawn. If the ESP needs more, it will draw more.
Esp needs more I am sure, because Esp01 is not working but When I connect to Esp 01's 3.3V and CH P- pin to Raspberry Pi Pico's VBUS it is working without any problem.
Add the RST pin to that 3.3v, most ESP-01's have a pullup resistor to RST, but not all of them do.
I have never use this RST pin but as I said with Raspberry Pi Pico's VBUS Esp01 is working good ill it cause a problem If I keep using this VBUS pin ?

Coming from Pico's VBUS, I am using Esp01 for http get and post. I will take data and make something with datas ( with HX711 and servo).
I don't know the DMM (and means), I just beginner hich program should I use for posting a circuit diagram? ( I will install and do that )
Hi @neveregret
DMM == Digital MultiMeter.
Draw you circuit using pen(cil) and paper, then post an image of it.
Tom....
here is my connection (If you if you understand my handwriting 
) (I am using LM 1117 TO-220 package)
I am using DMM for measuring Volts and currents.
So that would be !
LD33v|300x130
with this pinout. To be honest, i am sure that a LM1117 3.3v in TO-220 regulating down from 5v will provide you with the power you need. Check all connections, or even better, remove everything and start over.
Yes I did my connection for this. I can get 3.3 V but I don't get enough current I guess. I am measuring with DMM , Voit give 3.3V and 92mA. Should I just ise pico's VBUS (5V) instead of LM1117 ? Because as you can see my esp01 is not working with lm1117 I don't know why
What are you using for the 5V power supply? Where did you measure 200mA?
If it's a cellphone charger, then that could be your problem.
I am using raspberry pi pico's VBUS ( When I measure VBUS it gives 5.1V 200mA)
It is basically connected to USB, and can provide up to 500mA. Again, and someone has mentioned it before, when you measure current, you are measuring what your circuit is using not what it can provide.
You guess, but not correctly.
The circuit should work, so hence my suggestion. Disconnect all, and re-connect all.
How about you post a picture of your setup You wouldn't be the first to miss a connection somewhere. I have done that more times than i can remember. Just the other day i put a Pro-Micro on the breadboard, and it didn't work, turned out there was still a jumper connecting 2 pin (and 1 was RST and the GND)
Since you have already done that, it is quite possible your ESP-01 is already fried. (actually quite a likely scenario)
Okay Deva_Rishi I ordered New Esp01 I will try on monday. I will post it here if i get Esp01 worked or not and I will post my connection . Thank you.
Hi,
Did you measure the 5V input to the 1117 when the problem is present?
Can you please post an image of the 1117 assembly in your project?
Tom....
Surely you do not order them singly! 
I suggest four to start with:
I doubt it will break the budget. 
i order them 50 at a time.
You would! 
My new esp01 working even with Raspberry pi pico's 3.3V Should I use LM1117 or raspberry pi pico's 3.3V ?
Esp-01 came and working good even Raspberry pi pico's 3.3V
My new Esp01 working really good even with Raspberry Pi Pico's 3.3v. should I use raspberry Pi Pico's 3.3V or LM1117 ? Thank you.
