dc dc converter consumption
I have build a motorycle alarm and i used LM317 to reduce voltage from 12V to 5V DC. This alarm is using a microcontroller (AVR AT90s1200A) and i am having problem when the motorcycle is moving. To be more specific, when motorcycle is moving, the microcontroller is acting strangely, doing resets, running code that souldn't be running e.t.c.
I have come to the conclussion that there is to much noise to the power supply (to motorcycle's battery) when the motorcycle is moving or when i use the ignition.
What can i do? I do not want to use a dc/dc pulse converter because they are not 100% efficient and in this project the power consumption is very critical. I want a power supply circuit that has very low self power consumption
Can anyone help me? I am depserate
