Help with voltage regulator


Recommended Posts

Hello everyone i'm new to the forum and am looking for help with building a low cost voltage regulator that will regulate an input up to a maximum of 37VDC the output needs to be a voltage compatible with charging a 12 v lead acid battery so i'd guess around 13VDC The components would need to handle 10 A. Basically I came across a broken solar panel that I repaired and would like to use it to charge a 12v battery and then use the battery to run an inverter. Any help on a cheap solution would be appreciated.

What's the minimum input voltage?

The LM317 will do. It'll need additional components to work up to 10A. A siwtching regulator is probably the best solution for you. Refer to page 19 of the datasheet. You'll need to uprate the components in the examples to get it to work up to 10A.
