    I just saw the add for Maxim's new chip line of AC to DC
converters. Just a couple of resistors and one cap. and you can
connect it directly to 110 volts AC and get 5 volts DC regulated
to within 4%. It also has a power on reset circuit built in.

   Such a deal!  Very useful in certain situations.  THe big
question is:   What are the UL problems with this, if any?  Does
UL require power line isolation? 

   There must be some standards people on the net who would know this.
