Voltage is about 16 K ohms. However, I cannot turn on more than 4-5 before they start switching off. Remarkably, the 3.3 V no load voltage is higher, and as voltage drops below 2.9V the A460s refuse to turn on. They turn on and off.
For the 5V it looks as if the load voltage is about 5.25V and some of them refuse to turn on.
I would say that 3-4V is a safe operating voltage range..
This is quite frustrating as I have 2 voltages on an extreme. I cannot put them in parallel as there will be a giant short due to the low internal voltage.. I am looking at 2N3055 NPN BJT for a 0.7V drop across the 5V terminal. Any experience with this ? It is rated for 115V..
