Semiconductor
A431x
Programmable Voltage Reference
Description
The A431 series are 3-terminal precision shunt regulators that are programmable over a wide voltage range of
2.495V to 16V with 鹵0.5%, 鹵1.0% tolerance. The A431 series have a low dynamic impedance of 0.15鈩? These
features make the A431 series an excellent replacement for zener diodes in numerous applications circuits that
require a precision reference voltage.
