STK5445 Regulator chip data sheet.
Hello all !
Just really looking for some information here. I'm wanting to verify the operation of the regulator IC in an old video (an old Sanyo VHRS700E). I've had this old machine for a while now and by and large it has sat around unrepaired. From memory functions such as rewind/replay weren't operational or barely worked and some of the lights at the front of the unit weren't working either. The VCR itself uses a regulator chip model number STK5445 (in the PSU section). Though I cannot find any datasheet on the device online, hence the fact I'm stuck as to what I'm supposed to see coming out of it! I've read though I cannot recall where btw that these devices can be quite unreliable. Anyone have a datasheet for this device at all ?Thankies! ljoens |

Sanyo S700E eh.
I always fancied one of those. Sanyo's first centre loading deck that most other manufacturers followed thereafter. I have two of the previous VHRD4890E SVHS models. Pretty impressive and RRP were £1010 new. Kev |
