IRU431L General Description


The IRU431L family are three-terminal adjustable shunt regulators that can also be used as precision voltage references. Its output voltage may be set to any value between VREF(1.24V) and 15V with two external resistors as shown in the typical application circuit. Other applications of this device include being used as a merged amplifier and reference in applications such as a linear regulator or as the secondary side controller in low voltage power supply applications. The IRU431L only requires 80mA maximum quiescent current before regulating, making it ideal as a voltage reference for battery type applications. The IRU431L has 61% initial accuracy while IRU431AL provides 60.5% initial accuracy.
