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
