Description

      The SPX1432AM_TR is a three terminal adjustable shunt voltage regulator that provides a highly accurate 1.24V bandgap reference with 0.5% accuracy,eliminating the need for trimming in most power supply designs.Offered in the tiny SOT-23 package, the SPX1432AM_TR has an extremely wide operating current range of 60uA to 100mA, and reference input current of only 100nA (typ). The SPX1432AM_TR can regulate outputs from VREF to 20V, using two external resistors, and is guaranteed over the extended commercial temperature range of 0°C to 105°C.
      The combination of the small size, wide output current capability, flexible voltage range, and stable performance over the entire extended commercial temperature range, makes the  SPX1432AM_TR the ideal  candidate a variety of shunt regulator and current source designs in applications such as Portable meters, Instrumentation, and Industrial Process Control.
