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 ±0.5%, ±1.0% tolerance. The A431 series have a low dynamic impedance of 0.15. These features make the A431 series an excellent replacement for zener diodes in numerous applications circuits that require a precision reference voltage.
Features
Programmable output voltage from 2.495V to 16V Voltage reference tolerance : ±0.5%, ±1.0% Cathode current capability of 1mA to 100mA
