It is my first question on this site and I'm probably doing something wrong, try to be gentle! haha I want to provide 3.3V to my ESP8266 module from my Arduino, but people say this WiFi module requires more current than that 3.3V pin can provide. So I'm getting 5V from Arduino and turning it into 3.3V through LD1117 (just as it is done here http://iot-playground.com/2-uncategorised/17-esp8266-wifi-module-and-5v-arduino-connection).
This is the little guy. The problem is I can't get it to provide 3.3V. With no Resistor Load, output is 4.2V. With low Resistor Load (1k Ohm) just for the purpose of testing voltage does not keep at 4.2V, it drops, but it shouldn't, right?
I'm starting to think that maybe providing 3.3V directly from the Arduino isn't that bad of an idea. Can someone guess what I am doing wrong with this LD1117? Thanks in advance!
