SL432xM Semiconductor 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 a 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 from 1.24V to 16 V • Voltage reference tolerance 1.0%, 2.0% • Wide operating current range of 60uA to 30mA Ordering Information Type NO.
