Hello
I have a device (a printer) which will work on 7.2V and requires about 2.5 amps. I need to design a circuit that will supply the voltage only when required. Hence i decided to use a transistor for the switching. I am not too sure which transistor to use. Can anybody kindly suggest me the option for the same. Or for that matter, will a simple switching circuit actually work for this configuration?
How about using TIP31.
Datasheet of TIP31 : https://www.electro-tech-online.com/custompdfs/2010/11/TIP31A.pdf
I have also attached the schematic that i am using now. Is it actually the right way to do for the required voltage and current.
Your advice will be very helpful.
