SL431xM

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
