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 V

REF

to 20V, using two external resistors, and is guaranteed over the extended commercial temperature range

of 0擄C to 105擄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.
