431AL General Description

The US431L product is a 3 terminal adjustable shunt regulator that can also be used as a precision voltage reference. Its output voltage may be set to any value between Vref(1.24V) and 6V with two external resistors as shown in the typical application circuit. Other applications of this device include the use as a merged amplifier and reference in applications such as Linear regulator or as the secondary side controller in low voltage power supply applications. The US431L only requires 80uA maximum quiescent current before regulating, making it ideal as a voltage reference for battery type applications.
