PRODUCT DESCRIPTION
The SPX3431 is a 3-terminal Adjustable Shunt Voltage Regulator providing a highly accurate 0.5% bandgap reference. SPX3431 acts as an open-loop error amplifier with a 2.5V temperature pensation reference. The SPX3431 thermal stability, wide operating current (100m A) and temperature range (0°C to 105°C) makes it suitable for all variety of applications that are looking for a low cost solution with high performance. SPX3431 tolerance of 0.5% is proven to be sufficient to overe all the other errors in the system to virtually eliminate the need for trimming in the power supply manufactures assembly line and contribute a big Cost Savings. In the standard shunt configuration, the bination of low temperature coefficient (T.C.), sharp turn-on characteristics, low output impedance and programmable output voltage make this precision reference an excellent error amplifier. The SPX3431 is a direct replacement for the SPX431 and TL431 in low voltage, low current applications. SPX3431 is also available in SOT-89 and TO-92.
