jeroddumas Posted August 16, 2004 Report Posted August 16, 2004 I am using a 16vac power adaptor with my MBSID. The sid voltage regulator is fine, but the core is getting hot. Should I use a circuit with a 7809 to step down the power before going into the 7805, or should I just heatsink the 05 and let it be????

doc Posted August 16, 2004 Report Posted August 16, 2004 Hi,16Vac should be no problem for the regulator. It is normal that the regulator is getting hot. If you can't touch it - give it a heatsink.If there are no further problems, you just can " let it be"greetsDoc

kapser Posted August 18, 2004 Report Posted August 18, 2004 Well, mine voltage regulator was also very hot ( not normal hot ). Problem was that a placed some IC's on the DIN en DOUT board in the wrong way :-( So they seem the work as a diode or something. So unplug everthing on your CORE module ( all the external modules voltage lines ) and check if that solves your problem. If it is, then there is certainly something wrong with the external modules.

jeroddumas Posted August 21, 2004 Author Report Posted August 21, 2004 no the voltage regulator runs fine when using smaller voltage. Say 9vdc. But when I use my 16vac to power the core and the SID is when I run into problems with the regulator getting hot.
