Ouff, I am using Orcad to design my circuits and this one got me. I am using 2 diodes to protect an input line, one from ground to the line and one from the line to VCC. And my dear Orcad misplaced the diodes so mines where straight from VCC to the GND. Now I have to unsolder 16 (!) diodes and replace them. Thank you for taking the time to reply to my stupid question :) Lucian -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU] On Behalf Of Jinx Sent: 14 mai 2004 16:15 To: PICLIST@MITVMA.MIT.EDU Subject: Re: [EE:] Cascading Regulators > The pinout of the 7805 is IN-GND-OUT, when looking from its > front, isn't it ? (at least that's what I've found on the datasheets Correct. Maybe you've a bad 7805 (possible) or capacitor (unlikely). Do you have spares to substitute to find out ? You haven't mistakenly used a 7905 have you ? (just a long shot) -- http://www.piclist.com#nomail Going offline?
