SPX1431-Precision Adjustable Shunt Regulator
DESCRIPTION The SPX1431 is a three-terminal adjustable shunt regulator providing a highly accurate bandgap reference. The SPX1431 acts as an open loop error amplifier with a 2.5V temperature compensated reference. The SPX1431's thermal stability, wide operating current (150mA) and temperature range (-55°C to 125°C) make it a suitable type of application requiring a low cost, high performance solution. The SPX1431's 0.4% tolerance proved to be sufficient to overcome other errors in the system, essentially eliminating all need to trim the power supply manufacturer's line and contributing to significant cost savings. The output voltage can be adjusted to any voltage value between 36 VREF and two external resistors. The SPX1431 is available in TO-92 and SOIC-8, SOT-89 and SOT-23-5 packages.
