The resistance of the linear voltage regulator changes with the load and gives a constant voltage output. BEC Voltage Regulator – What is a BEC or voltage regulator’s purpose? Gas guys will go by the term voltage regulator. If you are running the ATmega238 at 5V using a 9 V battery, approximately half of the battery's energy will be dissipated as heat by the regulator. 5W) and the regulator got too hot to touch. Our low-dropout linear regulators support specific performance applications where switching voltage regulators are not the obvious choice, including:. 8 we have a Zener diode regulator for a negative polarity power supply. 5 A, very low drop voltage regulator 13 1. I'm currently looking at using a national Semiconductor LM2940 1A LDO linear regulator Here.
