$Features & Applications

The SPX2431AM-L/TR is a 3-terminal adjustable shunt voltage regulatorproviding a highly accurate bandgap reference. The SPX2431 acts as an open-looperror amplifier with a 2.5 V temperature compensation reference. The SPX2431’sthermal stability, wide operating current (100 mA) and temperature range (0°C to105°C) makes it suitable for a variety of applications that require a low cost,high performance solution

The SPX2431A tolerance of 0.5% is proven to be sufficient to overcome all ofthe other errors in the system to virtually eliminate the need for trimming inthe power supply manufacturer's assembly line and contribute a significant costsavings. The output voltage may be adjusted to any value between VREF and 20volts with two external resistors. In the standard shunt configuration, thecombination of a low temperature coefficient, sharp turn on characteristics, lowoutput impedance, and programmable output voltage makes this precision referencean excellent error amplifier

Features:

  • Trimmed Bandgap to 0.5% and 1.0%
  • Wide Operating Current 1 mA to 100 mA
  • Extended Temp. Range: 0°C to 105°C
  • Low Temperature Coefficient 30 ppm/°C
  • Offered in 3 Pin SOT-23 (M)
