TS4431 Datasheet (STMicroelectronics) - 1.224V Open Collector Shunt Voltage Reference

TS4431, 1.224V Open Collector Shunt Voltage Reference

The TS4431 is a four-terminal device dedicated to low voltage Switch Mode Power Supplies (SMPS).

It integrates a 1.224V voltage reference, an amplifier, and an open collector output transistor in a single package.

The TS4431’s operating mode is similar to the well-known standard voltage reference, t
