Folks, Hopefully this is the right place to ask this. I'm a software engineer with VERY limited EE experience and am trying to learn. At the moment, I've got a project that I'm trying to power using a 6v 6w solar panel, a load sharing solar battery charger, and a battery - though for this issue the battery is not in the loop. I'm also using a low drop out linear voltage regulator since based on the sun, voltages from the panel could vary.
When I plug the solar panel into the charger and take a voltmeter to the output leads, I get something nice and consistent around 5v (the panel is not in full sun at the moment). However as soon as I attach the voltage regulator (without any load) the voltage output from the charger goes pretty haywire jumping from 0 to 5. The output from the voltage regulator is around 1.8 or so. This definitely doesn't power my project since it needs 3.3v.
I'm using all purchased parts - didn't really design any circuit myself. The part list is above. Anybody know what is happening or how to get a consistent output? Thanks
