You can use the Pololu U3V12F12. Remember that the resistor between the power and the pin #16 should be 180R for +5V and 570R for +12V.
Thanks for the reply. Do you think this one is equivalent?

This is the specs in english
Super Mini DC Step-Down Module - 12V 24V to 5V Step-Down Module
The MINI Super Size (20 x 10 mm) DC Step-Down Converter Power Module is smaller and more efficient, using an integrated molded power inductor and synchronous rectifier control chip. This module can be used in various applications such as DIY mobile power, monitor power supply, power cars, camera power supply, car power, communication equipment power supply, and demanding applications (aerospace models, etc.) due to its precise size and weight.
