Subject: Need help to identify a chip

Need help to identify a chip

From: Linus Nielsen Feltzing <>

There is a voltage regulator on the iRiver H1x0 that I need to replace
on one of my units. I have so far failed to identify it, and I need help.

It is the chip U28 on the main PCB, located on the far low end, next to
the reset switch. It is marked "TXQ". You can see it in the pictures on
the iRiverInfo wiki page:

Texas Instruments and Maxim say that it isn't one of their chips.

Please help!
