TYPICAL APPLICATION
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 V
REF
(1.24V) and 15V with two external resis-
tors 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 80
μ
A maximum quiescent current before regu-
lating, making it ideal as a voltage reference for battery
type applications. The IRU431L has
±
1% initial accu-
racy while IRU431AL provides
±
0.5% initial accuracy.
