1-Can I use precision 1.5v regulator only to this job to generate the VCNTLP signal because I need only +1.5 v and 0.
2-if not possible above option above can I use the following modified version of design below in which I have crossed the parts which I do not need and by changing resistor values I will get +1.5v only ?let me know if this approach works for me .See snapshot below
