19v to 5v drop resistor value needed
Yes, I know that it's true but when I use a resistor in the place of the motor the L7805 is cold, and when I use the motor then it's hot.
I will try all that you said. Thanks for you help.
l7805 power supply
Hi to all!!!
I have made a board with a microchip (16f876) and a power mosfet IRF3205.
The mosfet drives a 3 A motor using a 24 V DC source. I'm using the PWM output from the PIC (0-5V) to adjust the mosfet from 0-24V. This speed control runs ok, but I'm using a L7805 to...
