Hi! All 78xx regulators I used had the pinout the way you said (I presume TO-220 housing ). They aren't that delicate, they aren't that expensive, so you could easily test our assumtion on one of them :-) Regards, Samo ----- Original Message ----- From: John Nall To: Sent: Thursday, March 13, 2003 11:20 PM Subject: [PIC]: 7805A pins > I'm kind of embarrassed at asking this, but I need a little help in > identifying the pins on a 7805a voltage regulator. :-( I can't find a > datasheet on it.
