SL431x
Programmable Voltage Reference
Description
The SL431 series are 3-terminal precision shunt
regulators that are programmable over a wide voltage range of 2.495V to 36V with ±0.5%, ±1.0% tolerance. The SL431 series have a low dynamic impedance of 0.15Ω. These features make the SL431 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 36V Voltage reference tolerance : ±0.5%, ±1.0% Cathode current capability of 1mA to 100mA
