Paul was actually referring to the voltage drop through the voltage regulator (LM317), not to allow for future demands. But , as an aside, I was supplying a few pc's not very much short of this spec 6 months ago to a number of clients. But if we're looking to the future: keeping pretty close to Moore's law with reg to processor speed.... Perhaps you meant 4Thz? 2TB RAM 100TB HDD wireless nic- 100Gbps and you forgot all embedded into a fabric form factor. now that sounds about right eh ;-) JJ -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of WH Tan Sent: Thursday, 29 April 2004 10:45 AM To: PICLIST@MITVMA.MIT.EDU Subject: Re: [EE:] Voltage regulator for 3V - 30V input to 3V or 5V Hi Paul, You're a man from the furture. Can you please tell me what is the spec of the PC you're using on that year. I really what to know it because I read from a newsletter that Microsoft's Bill Gates have recently share his view of PC at the time about 2017. He said that there will be over 4GHz in speed. And I think you should have over 2GB of RAM onboard because he said so. About the HD, I think you should have one over 100GB. Your network access must be over 100Mbps wirelessly.

If they are 1.5 A or less, you can use the LM317, adjusting the output voltage. You must provide 3 Volts more than the desired output in the input pin, to obtain a good regulation. It works well, and it is cheap ;) Regards, Paul H. Castro -- http://www.piclist.com hint: The PICList is archived three different ways.
