hello, anyone. Recently, i want to design a circuit of 0.75V reference voltage. i have researched the majority of the IC manufacturers' material, but i still cannt find a suitable design for my circuit.
could anyone offer some materials about the circuit design? thanks.

Why not a precision 1.2V or 2.5V reference and a resistive divider?

Do you need to draw any current from it?

How much precision and stability do you need?

If you need little of either, then a forward biased diode may be close enough.

What is it for and are there any more details you could give us in order to help you?

hello, steve.you are very enthusiastic. thanks for your reply."Why not a precision 1.2V or 2.5V reference and a resistive divider?" i think this approach is not good, cause it has no high precision. in this circuit, there is no current consideration. i am trying to find a single IC for my design. that's to say, IC specifications: 5V input, 0.75V output. any ideas?

I would suggest a precision 1.2 or 2.5V reference and precision resistors to make a voltage divider.

You don't mention the precision you require nor the purpose that you require it.

There is a reason that you find 1.25V as the lowest precision reference.

that's ok. thank you, steve. i decide to di it as you recommended:a precision 1.2 or 2.5V reference and precision resistors to make a voltage divider. maybe it's the best way so far. really thanks.
