So you got enough ripple space still, 3.8V at 5A. 2.5V DC across D11 is the wise lowest limit.
For what you want it for that draws many Amps at 5V?

Aha, what you used for test load? Electronic programmable load, heavy resistor, automotive light bulb?
Your mini computer has 12V default DC spec though I see. But accepts 5-20V rail. Maybe wiser to spend less amps and work at 12V?
Raxda Rock 5b+:
- 5V through GPIO
- yes - 9,12 and so on volts could be connect to USB Type C
My new project has 2 x 6J5, and I have 2 x power transformer, and each has one 9vac @1A winding other than the HV winding. Can I use L-Adapter for regulated filament supply?
Dears,
If I understood well according to this
'' 2. Select 2 times more VA transformer spec than the load Watts when for below 14V rail. For example, a 5V 2.5A RPi rail is 12.5W peak capable. Thus don't use smaller than 25VA''
For RpI 5 (5V-5A-27W Original PSU) I must put a 50- 60VA transformer?
Storage capacitors: For up to 50W peaking loads 6800uF C3 C4- 6800uF enough or 10000uf is better to use?

10000uF is better for this, 50-60VA is better for this. Although 5A is the max pull when fully kitted out and all its USB outputs feeding peripherals I would think.
Hi. Can i use L-adapter with just a green led to supply the 1.3V DVDD pin?
I mean will be the voltage stable at this very low level?

Hi,
I remember it stable enough from 1.5V upwards, not sure about same stability at 1.3V but it adjusts that low, you got to check.
