shaiqbashir Posted March 18, 2006 Report Share Posted March 18, 2006 HI Guys!well! my dear friends!Im making a robot. In which i will be requiring 5V for a motor. I have a 12VDC, 5AH battery.Now how i will supply 5V to a motor from a 12V battery. Should i use a regulator 7805. Will it be able to handle an input voltage of 12V??????and one thing that i was also thinking is this that first i use 7809 regulator to regulate the battery voltage to 9V and then use 7805 to further regulate that 9V to 5V.And what about the curent ?i mean my stepper motor requires 1.4A per phase of current. so It will be around 5.6A total requriement. Will the regulator be able to supply such a high current.If not what should be the best method to do that.I shall be thankful to u if u will make an eary replythanks in advance Quote Link to comment Share on other sites More sharing options...
