At my work they use Programmable Voltage Reference chips TL431IZT for the IC chips around a CPU microcontroller
They use a Programmable Voltage Reference TL431IZT to power a SC-531P Oscillator 8.0 MHZ
But why did they use a Programmable Voltage Reference TL431IZT , what does it do? why didn't they just use a voltage divider with resistors and trim pot?
If you put a lot of load on the output of a TL431IZT it doesn't drop the voltage? why is that? is it like a regulator?
What have you seen Programmable Voltage Reference used for? why did they use them?
