is it possible to get higher output voltage "stability" by cascading voltage references?
-- REPHRASING --
Suppose I have IC1 and IC2. Both are 0.5% accurate TL431 parts. IC1 takes 15V and outputs 12V. This is fed to IC2 and IC2 outputs 5V. Will the 5V output from IC2 be more stable, than if this output was directly taken from IC1?
Output current is well within the limit, and my main concern is line-regulation?
Thanks in advance,
