Semtech SC431L Low Voltage Adjustable Shunt Regulator Datasheet
The SC431L is a low voltage three-terminal adjustable shunt regulator designed with thermal stability guaranteed over temperature. The output voltage can be adjusted to any value from 1.24V to 20V using two external resistors. It features a typical dynamic output impedance of 0.25Ω and is available in three voltage tolerances (0.5%, 1.0%, and 2.0%) and three package options (SOT-23-3, SOT-23-5, and TO-92).
