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 ±0.5%, ±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
• Programmable output voltage from 1.24V to 16V
• Voltage reference tolerance : ±0.5%, ±1.0%, ±2.0%
• Cathode current capability of 80 ㎂ to 30mA
Ordering Information

1. Ambient temperature range: TLOW = -40℃, THigh = 85℃
2. The deviation parameters △Vref and △Iref are defined as the difference between the maximum value and minimum value
obtained over the full operating ambient temperature range that applied.
