They don't have the JR. but they say most versions are similar. This one has the charge pump.<br /><br />You can also use an ICL7660s or MAX1044 for a charge pump, pretty much interchangeably.motterpaulhttps://www.blogger.com/profile/15536330842070250774noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-42311761779746624712015-11-16T01:17:56.349+00:002015-11-16T01:17:56.349+00:00Post on the forum!

I couldn't find a 1054, but I went with the 1044, jumpered pins 1 and 8 and used a 9.1 zener. It was the current one for sale on the 1590A section of his shop.Ham-Phisthttps://www.blogger.com/profile/12420814240027254942noreply@blogger.com
