Guest Kasamiko Posted November 26, 2004 Report Share Posted November 26, 2004 I want to build this Potable PIC programmer but have question regarding the power supply section. The design of the power supply section based on LP2951 adjustable low dropout regulator seems overkill to me,since this chip (LP2951) is not available in my place, can I simply replace it with are more common 7805 regulator without affecting its performance?rhonn ;) ;) Quote Link to comment Share on other sites More sharing options...
MP Posted November 26, 2004 Report Share Posted November 26, 2004 You would not have the shut down/current limiting feature, but yes, most development boards for micros are built around one of the 7805 regulator chips. It will work fine for regulation.MP Quote Link to comment Share on other sites More sharing options...
Guest Kasamiko Posted November 26, 2004 Report Share Posted November 26, 2004 Since I dont need that extra feature this IC can offer I 'll go with 7805 instead... ;DThanks MPrhonn ;) ;) Quote Link to comment Share on other sites More sharing options...
