DESCRIPTION
The SPX432 is a 3-terminal adjustable shunt voltage regulator providing a highly accurate 1.24V
bandgap reference with 0.5% tolerance. The SPX432’s thermal stability, wide operating current
(80mA) and temperature range (0 ° C to 105 ° C) makes it suitable for a variety of applications. SPX432
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 manufactures’ assembly lines and contribute a
significant cost savings.
The SPX432 is an ideal voltage reference in an isolated feedback circuit for switch mode power
supplies. SPX432 offers many advantages over the TLV431 such as wider output voltage (18V vs.
6V), higher output current (80mA vs. 15mA) and a wider operating temperature range with a tighter
tolerance down to 0.5%.
