• Hi , the component in the picture attached is shorted and I need to change it. I cant find any data sheet for IC16C. The marking in the board reads VR1, so I believe it is a voltage regulator. But what type?.
  
  Thank you all in advance.
  
  PD. the component is in an old IPOD Hifi speaker.

• Hello, maybe this TPS76316DBVT?
  Does the pin diagram match or not?

• Be aware that the source of the short may be after the regulator.

• CapDon, I used a thermo camera and this component is getting hot. Makes alcohol evaporate right away.

• But It will get hot if there's a short at the output.

  I will remove the two components that gets hot one at a time and recheck to find out which one of the two it is shorted.
  
  Muchas gracias.

• Marking "IC" could be a "RT9167-27CBR":

  Don't crop the image so much, the surrounding parts can give some hints.
