Thanks Ron. Considering lower than design input voltage (12 vdc vs. 30 vdc), wouldn't that reduce Vref that LM723 sees (compared to it's required 7.15v), and wouldn't I need to change some resistor values (which ones) to compensate for it?
Also the one-third potentiometer travel is not at the...
Hi! My LM723 based 0-30 VDC regulator kit (see circuit diagram below) requires 30 VAC input transformer but I only have nominal 12 volt transformer instead of the required 30 VAC input. Using this 12 volt 3 amp transformer operating at line voltage of 230 volts, I get 0.25-22.4 VDC output...
