Speaking of LDO: I still haven't found the "perfect" one. I recently found this one: TPS7150 http://www.ti.com/product/tps7150"...Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (maximum of 32 mV at an output current of 100 mA for the TPS7150)... ". Sound really good. What do you guys think?Which LDO would you recommend?
Start with your requirements and do a filtered searchat one of the distributers' websites that allows parametric search.
Adafruit seems to use a diode on the Adafruit HUZZAH ESP8266 Breakout board to connect 5V TX to 3,3V RXhttps://learn.adafruit.com/system/assets/assets/000/024/745/original/adafruit_products_schem.png?1429900999They us a 1 N 4148. Is this a good solution?
