Constant current sink regulation of 1/R1. Figure 2 illustrates how a fixed voltage divider might be used (assuming a 5-V rail that’s accurate enough) to use a floated-anode Z1 to regulate a constant ...

In principle, TL431/TS431 provides a reference that is more stable than the 78L05! Anyhow it’s pointless to use this module unless you know how to run it properly. Let me show the (believed to be ...

If you don’t know the TL431 (aka LM431), ... It was based on a constant current source that is controlled by a DAC hooked up to the Arduino.

This shows that the biasing current of the TL431 not only varies with the load ... 1 = 9.64 V. Knowing that V OUT is constant at 12 V, then imposing a 1-mA current via R bias will lead to R ...

To avoid the need for feedback components, the power stage uses a constant current source design. This allows a shunt, such as the TL431 or even a simple zener clamp, to provide output voltage ...
