US431ALCL - Low Voltage Adjustable Precision Shunt Regulator
Description The US431L product is a 3-terminal adjustable shunt regulator that can also be used as a precision voltage reference. Its output voltage can be set to any value between the voltage Vref (1.24V) and 6V with two external resistors as shown in the typical application circuit. Other applications of the device include use as a combined power amplifier and reference at the time of application, such as a linear voltage regulator or in low voltage secondary side controller power supply applications. It only needs to be regulated before the US431L's maximum quiescent current is 80uA, making it an ideal battery-type voltage reference application.
