TYPICAL APPLICATION
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 appli-
cations of this device include the use as a merged am-
plifier and reference in applications such as Linear regu-
lator 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.
