Hello all,
I'm considering a upgrade from the standard raspberry pi 4 switching-mode power supply (Buy a Raspberry Pi 15.3W USB-C Power Supply – Raspberry Pi) to a low noise power supply in order to take the most advantage of the HF SDR equipament connected to it.
I have a switching-mode power supply from my previous HF trasnceiver: 15V, 30AMP PS. Thus I thought of using a linear regulator connected to this power supply, setting the output voltage to 5.1V. I'm currently looking at LM138/LM338 regulators.
What are your advice?
Better to get a dedicated PS from the 230V mains for the raspberry pi to minimize the noise?
Thank you in advance
