The LDS431LP is a low voltage reference/amplifier suited for the control loop of low voltage power supplies. Functionally similar to the ubiquitous TL431, the LDS431LP has a lower 1.24V reference and a much wider range of operating currents. Particular care was taken in the design to minimize overshoot at startup and to allow wide AC bandwidth. The LDS431LP is a drop in replacement for any 1.24V shunt reference.
