alkv23 Posted August 19, 2005 Report Share Posted August 19, 2005 hi friend im new to electronic and like to ask how to step down current from 12vdc to 9vcd,24vdc to 19vdc, 9vdc to 5vdc and many stepdown. What the components using for stepdown and plz show me some schematic on this matter. Thanks hope i will get reply from u all. Quote Link to comment Share on other sites More sharing options...
ante Posted August 19, 2005 Report Share Posted August 19, 2005 Hi alkv,You like to step down these voltages not currents. The question is: how much current do you need on those voltages?If the current requirements are not too high, you should look at LM7809, LM7812 and LM317 for a start.

waferstar Posted August 19, 2005 Report Share Posted August 19, 2005 yes,agree to AnteAnd if you want to from 5V DC to 3.3V DC ,you also can use the diode to step down the voltages.Of couse if you use the 7805,7812,You should consider the overheated.
