Description

The SPX1432 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 SPX1432 has an extremely wide operating current range of 60uA to 100mA, and reference input current of only 100nA (typ). The SPX1432 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 SPX1432 the ideal candidate a variety of shunt regulator and current source designs in applications such as Portable meters, Instrumentation, and Industrial Process Control.
