GENERAL DESCRIPTION

The AMS431L is a three-terminal adjustable shunt regulator with guaranteed temperature stability over the entire range of

AMS431L features 0.5% initial tolerance, low dynamic output impedance and operates over a wide current range. Due to the

sharp turn-on characteristics this device is an excellent replacement for zener diodes in many applications.

AMS431 is available in TO-92, SOT-89, 3 pin SOT-23 and 5 pin SOT-23 packages.
