Re: Raduino transistor getting hot

MVS Sarma

Following possibilities are to be considered.

We can divert  the back-lit circuit of LCD to unregulated voltage with higher series resistor.

The datasheet for7805 indicates around 3V . Now we have 7 or 8V and the load current  might be around 1 amp.We can mount  it on a heat sink.
Thus we can also have a input 12 or 13.8V through a 5 ohm 5 watt resistor  and it helps reduce the input/ output differential of the regulator.
