Semiconductor
SL432xSF
Programmable Voltage Reference
Description
The SL432 series are 3-terminal precision shunt regulators that are programmable over a wide voltage range of 1.24V to 16V with 1.0%, 2.0% tolerance. The SL432 series have low dynamic impedance of 0.25Ω. These features make the SL432 series an excellent replacement for zener diodes in numerous applications circuits that require a precision reference voltage.
Features
• Low voltage operation 1.24V • Programmable output voltage f.
