DC Converter 12V to 5V 500 mA

First of all, sorry for my poor english (I’m french). I looking for a DC converter 12V to 5V 500mA (output) and if possible with usb connector (output).
Is there someone who can help me please ?

@jpc Sorry for the late reply. The issue is that the onboard USB requirement greatly reduces the selection. You can find all 5V (output) voltage regulators here:
Some examples of those which include a USB output:
