SPX1432

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 V_REF 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.
