description/ordering information

The TL430 is a 3-terminal adjustable shunt regulator, featuring excellent temperature stability, wide operating

current range, and low output noise. The output voltage can be set by two external resistors to any desired value

between 3 V and 30 V. The TL430 can replace Zener diodes in many applications, providing improved

performance.

The TL430C is characterized for operation from 0°C to 70°C.
