CAT431L Datasheet (Catalyst Semiconductor) - Low-Voltage Adjustable Precision Voltage Reference

CAT431L, Low-Voltage Adjustable Precision Voltage Reference

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.
