The SPX2431L acts as an open-loop error amplifier with a 2.5V temperature compensated reference. The SPX2431L's thermal stability, wide operating current (100mA) and temperature range (0°C to 150°C) makes it suitable for a variety of applications. SPX2431LA tolerance of 0.5% is proven to be sufficient to overcome all the other errors in the system to virtually eliminate the need for trimming in the power supply manufacturer's assembly lines and contributes a significant cost savings. In the standard shunt configuration, the combination of a low temperature coefficient, sharp turn on characteristics, low output impedance, and programmable output voltage makes this precision reference an excellent error amplifier. The SPX2431L is available in TO-92, SOIC-8, and SOT-23-3 package. BLOCK DIAGRAM Cathode (K)...
