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.
