PRODUCT 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 thermal stability, wide operating current (80mA) and temperature range (0
°
C to 105
°
C) makes it suitable for
abroad range of applications.
SPX432 tolerance of 0.5% is proven to be sufficient to overcome other errors in the system to
virtually eliminate the need for trimming in the power supply manufactures assembly line and contribute a significant cost
savings.
The SPX432 is an ideal voltage reference in an isolated feedback circuit for 3.0V to 3.3V switching mode power supplies. SPX432
offers many advantages over TLV431, such as, wider output voltage up to 18V vs. 6V, output current of 80mA vs. 15mA, and a wider
temperature range with tighter tolerance down to 0.5%.
