ESP8266 ESP-01 with level-down/buck converter

Hello.

From what I've read:
Arduino has 5v and 3.3v outputs, so to use the ESP8266 you'll need to use 3.3v. But if you use 3.3v you won't get enough current (ESP8266 requires 200-300 mA but you'll only get 50mA from the 3.3v).

Along with my arduino nano and ESP8266 ESP-01 I also have a 5v to 3.3v level-down/buck converter that looks like this.

Will that be enough to get this to work ?

I'm very new to this. Thank you.

Read the datasheet for the IC that is used on the converter.
That should tell you what you need to know.
