I'm after your views on whether this regulator would be ideal for my application?
I am currently doing a project building an exhaust valve controller. I am going to be building a custom PCB with the option of adding GPS geofencing and RTC features.
I'm looking at powering it with a ZXTR2105FQ regulated transistor. I was going to use a buck converter but I heard that if running GPS you need a quiet power supply and looking at the ZXTR2105FQ is designed for powering microcontrollers in an automotive environment.
My Arduino is measuring 34-37mA at 5v with the valve controller program running, and the ZXTR2105FQ is capable of running a continuous current output of 89mA with a 12v input. Adding the GPS and RTC features I wouldn't have thought it would add much more mA in the mix.
What do you all think?
