SOT89-3 regulator
I'm searching for the datasheet of a component which I think is a voltage
regulator and is from a 2 batery powered cd player which has several such components and which reference code as printed on is "GY139" and which photo is here : http://picpaste.com/GY139-bhTrEixQ.jpg Another similar component on the same board is marked "KY139". I have not been able to find anything with these part numbers. |

The KY appears to be either a 2SK211 or 2SK811 from what I can find. Dan |

I have not been able to find anything with these part numbers. I went to this SMD code page. http://www.marsport.org.uk/smd/mainframe.htmI clicked on G in the upper left, when the G page loaded, I paged down to GY, it shows 2SC2882Y in case style SC62. If you search SC62 or better SC-62, you get http://www.e-devices.ricoh.co.jp/en/...pkg/sot-89.pdf Does that match your part dimensions and make sense that it would be an npn gp amp hfe 160-320? I think gp is for general purpose. Mikek If that doesn't look right, get confused and look here, http://alltransistors.com/smd-search.php?search=GY |

Mikek If that doesn't look right, get confused and look here, http://alltransistors.com/smd-search.php?search=GY The 2SC2882Y differs quite a lot from the 2SD2403 given by Dan previously, though junction type and the hFE given seems fine. The one I have I'm not sure it is in good condition, which is why I would like to change it, is showing ~ 260 with my cheap meter. alltransistors.com says 2SD2003 for "GY" as keyword, so I need some confirmation. Also I'm searching for the meaning of the "139" marked on my device. |

The cd player I'm trying to repair is from 2001, so the 2SD2403 might be the most appropriate. |
