i am dealing with a RF remote control toy car.i want to use the output voltages from the receiver side and interface it to the PIC.the output voltages of the receiver are ranging from 6-8V.the questions are:
i want to use 7805 regulator to step down the voltage to 5V only.can it be done with the 7805 regulator?how much input voltage should be fed to 7805 so that it will maintain its output at 5V? (i am poor in reading the data sheet,sorry).
are CMOS and TTL compatible with each other?
can anyone help me?
