makiyang614 0 Posted June 8, 2017 Share Posted June 8, 2017 I have a very simple lm317 adjustable voltage regulator put together with a voltage display panel to monitor it. I wanted a 1.5v source to use with the flash circuitry from a camera without having to use lots of batteries. I have the terminals on the camera circuit wired to output and ground of my regulator. When I turn the camera circuit on however, it charges extremely slowly, and the display meter cuts out. If I turn the voltage up, the display comes back on and displays between 0 and 1v. lm317 has a heatsink and doesn't feel hot. Power is fine when connected to leds. I tried adding a resistor in series with the camera circuitry in case I was drawing too much current, but then nothing happens at all. Quote Link to post Share on other sites
