■
Low Cost Solution
The SPX431L is a 3-terminal adjustable shunt voltage regulator providing a highly accurate
bandgap reference. The SPX431L acts as an open-loop error amplifier with a 2.5V temperature
compensation reference. The SPX431Ls thermal stability, wide operating current (100mA) and
temperature range (0
°
C to 105
°
C) makes it suitable for a variety of applications that require a
low cost, high performance solution. SPX431L tolerance of 0.5% is proven to be sufficient to
overcome all of the other errors in the system to virtually eliminate the need for trimming in the
power supply manufacturer's assembly line and contribute a significant cost savings.
The output voltage may be adjusted to any value between V
REF
and 20V with two external
resistors. The SPX431L is available in TO-92, SOIC-8, SOT-89, and SOT-23-3 packages.
