Dear All,
I am using EM18 rfid reader. It working well with 7805 power supply where input is greater than or equal to 9 volt but if I am using 2576 5.0 fixed voltage regulator with output 5 volt and input is greater than or equal to 9 volt. It's range is reduced to just 1 cm while using 2576 based power supply while this is not the case with 7805 based power supply. When using 2576 based power supply I am using 100 uH inductor and there is no inductor with 7805 based power supply. Looking forward for positive responses.
Thanks
