DESCRIPTION
The CAT431L is a low-voltage three-terminal
adjustable shunt voltage reference with guaranteed
thermal stability over the industrial temperature range.
The CAT431L has a lower 1.24V reference and wider
operating current range than the widely used TL431
and TL431A shunt-regulator references. Compared
to the TLV431/A, the CAT431L 1.24V reference is two
times more accurate.

I
SMPS control loop
I
Shunt regulator
I
Low temperature coefficient voltage reference
I
Current limiting

3V Off-line switching regulators
Minimal overshoot at startup and wide AC bandwidth
make the CAT431L easy to apply in a wide set of
applications. When used with an opto-coupler, the
CAT431L is an ideal voltage reference in isolated
feedback circuits for 3V to 3.3V switch-mode power
supplies.
