SPX431-Precision Adjustable Shunt Regulator
Product Description The SPX431 is a three-terminal adjustable shunt regulator that provides a highly accurate 0.5% bandgap reference. The SPX431 acts as a reference for open loop and a 2.5V temperature compensated error amplifier. The SPX431 thermal stability, wide operating current (150mA) and temperature range (0°C to 105°C), can satisfy all varieties of applications that are looking for a low cost solution with high performance. The SPX43's 10.5% tolerance proved to be sufficient to overcome all other errors in the system by virtually eliminating the need for trimming in the power supply, facilitating a significant cost savings in the production line. The output voltage is adjustable between any value of 36 volts between VREF and two external resistors. The SPX431 is operating in the 0°C extended temperature range to 105°C. The SPX431 is available in TO-92, SO-8, SOT-89 and SOT-23-5 packages. ...
