The SPX2431L is a 3-terminal adjustable shunt voltage regulator providing a highly accurate
bandgap reference (0.5%) and extremely low operating current (100碌A(chǔ)). The SPX2431L acts
as an open-loop error amplifier with a 2.5V temperature compensated reference. The
SPX2431L's thermal stability, wide operating current (100mA) and temperature range (0擄C to
150擄C) makes it suitable for a variety of applications. SPX2431LA tolerance of 0.5% is proven
to be sufficient to overcome all the other errors in the system to virtually eliminate the need for
trimming in the power supply manufacturer's assembly lines and contributes a significant cost
savings.
In the standard shunt configuration, the combination of a low temperature coefficient, sharp
turn on characteristics, low output impedance, and programmable output voltage makes this
precision reference an excellent error amplifier. The SPX2431L is available in TO-92, SOIC-8,
and SOT-23-3 package.
