I am creating an add-on board for my raspberry pi. I want to power up the raspberry pi from a voltage regulator (LM-2576 o/p is 5v and 3-A). I also want to drive two dc motors, 3-servo motors, an ultrasonic sensor, and 4 proximity sensors. I am using two LM-2576 regulators: one is for the raspberry pi, the other is for the drive sensors and actuators.
I believe my regulator is safe, but the inductor is getting hot after a few minutes. Why is my inductor getting hot? According to the data sheet I am using, it is 100microhenry and can support 3A at 5V.
Is the LM2576 sufficient for the raspberry pi and other sensors?
Is there a regulator available that I can replace both of my LM-2576 regulators with?
