GENERAL DESCRIPTION
The AMS421 is a four-terminal adjustable open collector shunt regulator with guaranteed temperature stability over the entire
range of operation. The output voltage can be set to any value between 0.5V (V
REF
) and 15V by adding two external resistors.
The AMS421 features 0.25% 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.
AMS421 is available 5 pin SOT-23 packages.
