Voltage regulator to give 2.5V out from 3.3V in

lnotarpietro · ‎2024-11-04

I am designing an interface board where there is an ADC that needs two different power supplies (3.3V and 2.5V).

To minimize this board, instead of bringing the two power supplies from outside, I would like to bring only the 3.3V one and through a voltage regulator provide the 2.5V one.

Could anyone suggest a product that would be useful for this purpose?

Thank you.

Hello,

With a dropout voltage of 0.4V.

3.3V - 0.4V = 2.9V > 2.5V -> OK
